Rock Evolution Questions, Answered: Punchimp, Rubblet and the Best Aura in the Game

RockUpdated Oct 25, 2026

Rock is the element people ask me about most, usually in the form of a specific question: is Cobbledon worth T3, why is everyone pushing Punchimp, should I bother with Popa? So instead of another ranked list, this guide answers those questions one family at a time. Two facts frame everything. First, Punchimp's line ends in Rockwu, the strongest three-lane attacker in the game. Second, Rock's T4 Aura cuts the damage your whole team takes, and most experienced players rate it the best Aura of the five. That makes Rock a natural first element to take all the way to T4.

The short answer

T2: Rubblet, Gibber, Humbug, Ringtail, then Punchimp as the fifth. T3: Rockwu before anything else, then Rockshell and Clangnaga, then Rockzilla and Zenscarab. T4: Rockong, Meteorax, Terraton, then damage dealers.

Questions about the core families

Why should Punchimp be my first T3 when it looks average at T2? Because Rockfu is only a warm-up. At T3, Rockwu gains three-lane reach, its clones swing at two lanes at once, and it strikes Zobos that get too close as well, so a single attack can land three times. That mix of damage and toughness gets it into almost every team. Make Punchimp your fifth T2 so it is ready to become your first T3. One caveat: it has faded as a Horde tank since chips came back and waves were shortened, and Waveflutter's Sleep spreads from Rockwu itself, never from its clones.

Is Rubblet the tank to build, or Snoozebo? Rubblet's line is Rock's best tank and gains three-lane damage at T2, though plenty of players still run Snoozebo at that stage. The real question comes at T3, below.

Is Cobbledon → Rockzilla a trap? Partly. At T3 the beam simply reaches further along its lane and hits a touch harder, and Rockwu plus Rockshell already cover the tanking. You do it anyway for two reasons: it sets up Meteorax, which no other Rock tank matches at the front of a Gold Rush team, and it lets you retire Snoozebo. Horde is playable thanks to self-healing and Stun, though late waves need more damage than it brings. If Horde and bosses matter more to you than Gold Rush, take Humbleetle first.

What does Gibber's line actually do? Its spinning shell pierces without limit. Park Turtuff behind a tank like Rubblet and the shell's shield keeps the tank alive longer. At T3, Rockshell shields every ally the shell passes through, and it is cheap to evolve. Its Horde Lv 7 was buffed, though the shells hit fewer Zobos than you would like. At T4, Terraton is the priciest Tatari in the game (nine food levels), so start feeding early even if you cannot finish yet; Gold Rush teams lean on it because it keeps front-liners standing and saves energy cans.

Taptail or Humbug for damage? Both, eventually. Taptail's bursts of attack speed give solid single-target damage, but its splash only touches the same tile, so it waits for T3, where Clangnaga's rapid waves pierce everything in the lane and it can hold a lane by itself (story, Dojo and Boss Challenge). Humbug is the best Rock damage against Zobos that stand still: Humbleetle keeps two dung balls on the field, Zenscarab three, and the Lv 7 whirlpool in Horde pulls Zobos together for heavy damage. Two of them can bring a Horde boss nearly to a stop.

And Ringtail? Rizzler sends out lackeys that tank and deal damage, and when they come back they heal and buff allied attack. T2 widens the buff area, and the Lv 7 Horde cannon takes a big chunk out of bosses. At T3, Zorrock's area grows to 3×3. It is strong for a T2, but Punchimp comes first.

Questions about the niche families

Should I evolve Popa? Not as a tank. It buffs one ally (two at T3, three at T4, the only T4 that changes its kit), but it cannot attack until it has taken a rising number of hits, and when it does attack it goes invisible and lets Zobos walk past. That is a disaster in Gold Rush. Some Horde use at Lv 5 and Lv 7; it never replaces Rubblet or Cobbledon.

Gopher, Drilleroo, Joeyo, Shardsnail? All Boss Challenge or Horde tools. Watchroo hides and stops attacking once Zobos get near, so it lives in Boss Challenge (Bastogard adds Blind). Drilleroo's reach is too short to be useful, except that Cragolin and Borelord can pin Frankenfish between two lanes in Boss Challenge so you only defend those lanes. Joeyo, once the weakest unit in the game, was revived by Horde buffs; its charged punch gains range and applies Fragile, but it is unused outside Horde. Shardsnail summons a tough crystal at the start of a fight and does little afterwards; at T3 the crystal can come back after breaking.

What about Momopo? Skip it at every tier. One-tile reach, a weak shield, and it pauses to recover HP after each kill, which wastes time in Gold Rush and breaks formations everywhere else.

Questions about T4 order

Which Rock T4 first? Rockwu → Rockong. It is the most versatile unit you will own, and the damage reduction Aura means fewer cans spent in Gold Rush.

Then? Rockzilla → Meteorax (the Gold Rush tank, which also gets a big damage bonus in that mode) and Rockshell → Terraton when you can afford it. After those, Clangnaga → Dharmadder for Boss Challenge (Gold Rush is out because its Arena Factor is low) and Zenscarab → Hierotyrus for Horde. Zorrock → Phantothief looks promising as a Horde tank-support. Borelord, Bastogard, Kangachamp and Jewelsnail T4s are for scores; Lilypo → Gemmapo is not worth anything.

What will the trials cost me? A fan-maintained list of trial requirements shows that almost every Rock T3 asks you to spend 5,000 energy cans in Gold Rush (plus three stat raises), so Rock T3s ride on your Gold Rush budget. Drilleroo is the exception (70 treasures or 4,200 fertiliser). Every Rock T4 needs feeding to B quality and 120 treasures or 7,200 fertiliser, plus one extra: three 24-star Rock Tatari for Punchimp, Lv 7 in Horde five times for Rubblet, five Rock badges for Gibber, 200 catches in the Tatari Catcher for Humbug, 50 wishboxes for Gopher and Shardsnail. At T2, Punchimp and Gopher need a second copy, and Rubblet needs 300 Zobo kills.

Opening upgrades (T1 → T2)

S · Build these first

  • Rubblet

    Rubbletevolves into Cobbledon

    Cobbledon splits Rubblet's single beam into several AoE beams, so it holds the front while clearing wide. It appears in 763 of 2,420 saved Tatadex lineups.

  • Gibber

    Gibberevolves into Turtuff

    Gibber's spinning shell pierces through enemies; Turtuff adds a Shell Shield so it survives longer while it chips away. We count Turtuff in 734 saved lineups, 202 from chapter 20 onward. At T3 the shield goes to every ally the shell passes.

A · Strong follow-ups

  • Humbug

    Humbugevolves into Humbleetle

    Humbug's dung balls stick around after landing and keep hurting whatever stands in them. Humbleetle adds Slow to that puddle, which pairs nicely with any burst damage behind it. It shows up in 326 saved lineups, including 39 on x-80 stages.

  • Ringtail

    Ringtailevolves into Rizzler

    Ringtail sends up to 3 Lackeys to fight in an area; each leaves after 5 hits, and on returning they heal and grant Vigilante: ATK Boost to allies nearby. Rizzler widens that zone. Data is thin: just 38 saved lineups include Rizzler, and only 1 is from chapter 20 on.

  • Punchimp

    Punchimpevolves into Rockfu

    Rockfu plays much like Punchimp, a light AoE hitter with an occasional clone, so the T2 itself won't change much. Evolve it anyway: the line ends in Rockwu, and Rockfu or a later form sits in 542 late-chapter lineups.

  • Taptail

    Taptailevolves into Rattlecoil

    Taptail opens with a couple of slow sound waves before rattling off a fast volley. Rattlecoil gives that volley a small splash and a chance to Stun, and the T3 lets the waves pierce. Rattlecoil already features in 80 lineups past chapter 19.

C · Low on the list

  • Popa

    Popaevolves into Popapouch

    Popa's line is a support with a twist. Popapouch hands its baby to one ally for Possum: ATK & DEF Boost, carries a Possum status that lowers both the damage and the healing it receives, and now and then plays dead to deal AoE damage around it. Popagrind passes the baby to 2 allies instead. Not one of the 2,420 lineups saved on Tatadex uses any form of this line, so nothing in the data argues for evolving it early; pick it up only if you want to experiment.

  • Gopher

    Gopherevolves into Watchroo

    Gopher lobs mud from a short distance, but once enemies get close it stops attacking and burrows for damage reduction. Watchroo keeps that trade-off, and Bastogard adds an occasional Blind. Only 21 saved lineups use Watchroo, and 10 of those are Rock dojo runs.

  • Joeyo

    Joeyoevolves into Puncharoo

    Joeyo just throws punches. Puncharoo learns to charge them, gaining damage and reach the longer it winds up, and a full charge leaves the target Fragile; Kangachamp sometimes skips the wind-up entirely. Fun on paper, but Puncharoo has 18 saved lineups and none from chapter 20 onward, so it stays near the bottom.

  • Shardsnail

    Shardsnailevolves into Gemsnail

    Shardsnail opens every fight by planting a Crystal Cluster just in front of your deploy area, and the crystal shares the snail's high defence. Gemsnail's shards add a resonance splash as they fly, and only Jewelsnail brings the crystal back after it breaks. Gemsnail appears in 86 saved lineups but just 8 from chapter 20 on.

  • Drilleroo

    Drillerooevolves into Cragolin

    When Drilleroo lands its heavy swipe, Zobos get knocked over to the next row, and any that can't be moved get Shredded instead. Cragolin's version also stuns. Only 11 saved lineups feature Cragolin, 2 of them on boss pages.

  • Momopo

    Momopoevolves into Lulupo

    Momopo blows kisses that hit an area, but it stops attacking after each kill to heal. During that break Lulupo also gets a Pink Shield. With only 8 saved lineups using Lulupo, it's one of the Rock T2s you can safely skip.

Core upgrades (T2 → T3)

S · Build these first

  • Rockfu

    Rockfuevolves into Rockwu

    Rockfu on its own is a modest club-swinger that only sometimes calls a clone. The payoff is Rockwu, whose staff spin brings clones that attack in sync, and our records show why it heads Rock: Rockwu or Rockong appears in 518 of 739 lineups from chapter 20 onward and in 94 of 196 x-80 clears. Make it the first Rock T3 you finish.

A · Strong follow-ups

  • Turtuff

    Turtuffevolves into Rockshell

    Turtuff already earns a spot as a T2: it is in 734 of our lineups, 202 of them past chapter 20. Evolving it changes who gets protected. Its piercing shell stops shielding only itself and hands a Shell Shield to every ally it flies past, so Rockshell pays off most with teammates sharing its lane.

  • Rattlecoil

    Rattlecoilevolves into Clangnaga

    Rattlecoil fires a few slow sound waves, then a quick burst with a chance to stun. At T3 that burst learns to pierce, which is the whole reason to evolve it. Clangnaga belongs to the late game: 90 of its 91 appearances come from chapter 20 or later, usually from the third or fourth row.

  • Cobbledon

    Cobbledonevolves into Rockzilla

    Few Rock units are fielded as often at T2: Cobbledon shows up in 763 Tatadex lineups. Rockzilla keeps the beam attack and adds an occasional heavy hit, and it stays a front-liner, with rows 1 and 2 as its usual spots. It counts 108 appearances past chapter 20 and 25 on x-80 stages, so it is worth the upgrade once your damage T3s are done.

  • Humbleetle

    Humbleetleevolves into Zenscarab

    On paper Zenscarab reads exactly like Humbleetle: dung balls that stick around, chip at everything nearby and slow it. What you are buying is the stat jump. Every one of the 52 Zenscarab lineups we have is from chapter 20 or later, nearly all from the back two rows, so treat it as a late investment, not an early one.

B · Good in the right team

  • Rizzler

    Rizzlerevolves into Zorrock

    Rizzler sends lackeys out to deal area damage, and when they come home they heal and pump attack for allies in range. Zorrock only enlarges that damage. We have just 4 Zorrock lineups, which is why it sits as an optional sixth pick rather than a core one.

  • Cragolin

    Cragolinevolves into Borelord

    Cragolin's heavy swipe stuns and shoves Zobos into a neighbouring row, or shreds the ones that can't be moved. That control is its identity, and Borelord mostly enlarges the swipe. No Borelord has turned up in our 2,420 lineups yet, so evolve it only for a fight where pushing enemies around is the plan.

  • Watchroo

    Watchrooevolves into Bastogard

    Watchroo lobs mud from range but goes underground the moment Zobos get close, trading damage for damage reduction. Bastogard adds an occasional Blind and keeps that same habit. One lineup in our records uses it, none past chapter 20; a pick for specific ranged setups only.

C · Low on the list

  • Popapouch

    Popapouchevolves into Popagrind

    Popagrind's change is simple: the baby buff now goes to two allies instead of one. Everything else, from the damage reduction it carries to the play-dead AoE, stays as it was. Not a single Tatadex lineup fields Popapouch or anything above it, so there is no evidence yet that it beats a regular Rock tank.

  • Puncharoo

    Puncharooevolves into Kangachamp

    The upgrade gives Kangachamp a chance to skip the wind-up and land a fully charged punch, which is also when Fragile goes out. It is a small edge. Puncharoo shows up in 18 of our lineups and none of them are past chapter 19; nobody in our data has taken it further.

  • Gemsnail

    Gemsnailevolves into Jewelsnail

    Gemsnail's crystal cluster appears once at the start of a fight; Jewelsnail grows a new one each time the old one shatters. That sounds handy, yet only 2 of our lineups use the T3, against 86 for Gemsnail itself, mostly in earlier chapters. Leave it until the real priorities are done.

  • Lulupo

    Lulupoevolves into Lilypo

    Lulupo stops attacking after each kill to sit behind a Pink Shield and heal. Lilypo makes that shield burst for area damage when it fades, but the pause is still there. With 8 Lulupo lineups and zero Lilypo ones in our records, it belongs at the bottom of the Rock queue.

The final step (T3 → T4)

S · Build these first

  • Rockwu

    Rockwuevolves into Rockong

    Rockwu is the most fielded Rock T3 we track, at 900 lineups, and it appears on four of the five boss pages. Rockong keeps the clone kit and brings the Rock Aura, which cuts damage taken for the whole team. The first Rock T4 should be this one.

A · Strong follow-ups

  • Rockzilla

    Rockzillaevolves into Meteorax

    A front-row anchor in our lineups, Rockzilla stands in row 1 or 2 most of the time and has helped clear 25 x-80 stages. Meteorax beefs up both the beams and the heavy hit, and adds the damage-cut Aura on top.

  • Rockshell

    Rockshellevolves into Terraton

    Rockshell lives mostly in late content: of its 129 lineups, 98 come from chapter 20 and beyond, plus 21 Rock dojo clears. Terraton's shell still shields every ally it passes, and now the team also takes less damage thanks to the Rock Aura.

  • Clangnaga

    Clangnagaevolves into Dharmadder

    Clangnaga is almost never seen before chapter 20, but after that it shows up steadily (90 lineups), usually in row 3 or 4 where its piercing waves have a full lane to travel. Dharmadder adds no new trick beyond the Aura, so evolve it when you want the stats.

  • Zenscarab

    Zenscarabevolves into Hierotyrus

    All 52 Zenscarab teams in our records are late-chapter ones, and the beetle almost always sits in the last two rows, lobbing slowing dung forward. Hierotyrus brings stats and the Aura, nothing more; worth doing after the Rock front line.

B · Good in the right team

  • Zorrock

    Zorrockevolves into Phantothief

    Phantothief changes nothing in the lackey routine and simply carries the Rock Aura. Since Zorrock appears in only 4 of our lineups, spend on it last among the Rock supports.

  • Popagrind

    Popagrindevolves into Popafam

    Popafam hands the baby to three allies, so the buff actually spreads further at T4, which is rare. Even so, we have no lineup using Popagrind or Popafam, so this one is for collectors and experimenters.

  • Borelord

    Borelordevolves into Armavolve

    No Borelord or Armavolve appears anywhere in our data. Its stun-and-shove swipe is still useful in a specific plan, but the T4 adds only the Aura, so there is no rush.

  • Bastogard

    Bastogardevolves into Cratzar

    Expect the same burrowing mud-thrower from Cratzar, now with the Rock Aura attached. Only one Bastogard lineup exists in our records, so its T4 is a luxury.

  • Kangachamp

    Kangachampevolves into Kaiseroo

    Kaiseroo punches like Kangachamp, instant full charge included, and adds the Aura. We have zero Kangachamp lineups, so nothing in our data argues for pushing it.

  • Jewelsnail

    Jewelsnailevolves into Crystalsnail

    Crystalsnail regrows its crystal cluster like Jewelsnail did and adds the Rock Aura. With 2 lineups in total, one of them on an x-80 stage, it is a curiosity rather than a plan.

C · Low on the list

  • Lilypo

    Lilypoevolves into Gemmapo

    Gemmapo still pauses after every kill. No Lilypo has appeared in our lineups, which makes it the last Rock T4 to think about.

Tatadex verdict

With Rock, the easiest mistake Fox sees is evolving Punchimp too late. It doesn't stand out at T2, so many people skip it, yet it is the first T3 worth having. Making it your fifth T2 is just right.

The Rock aura is considered the strongest at T4, so if you must pick an element to push to T4 first, Fox leans towards Rock (tied with Lightning). Treat Rubblet as the base tank for the whole element.
