Badge Dojo · Water 2-4

On the same grid as 2-3, the focus is Skinklet alone in row 2 of the middle lane.

Skinklet is a specialist that fires bubbles for area damage, turns invisible after taking enough damage, and goes after back-line enemies while hidden. In this layout it is the only unit in lane 2, standing between the strong lane 1 column and Swaystroll on the right.

Its cell is a connector rather than a wall. Enemies coming down the middle meet Skinklet at the same depth as Cribbler and Swaystroll, so the front stays even across the board. Its area bubbles also reach groups that Maskfry has pulled toward the edge of lane 1.

The invisibility changes how the middle behaves. When Skinklet hides, the enemies attacking it lose their target and keep walking, and nothing stands behind it. That is the moment the middle opens. In return, the hidden Skinklet goes after enemies further back, which can break up the next group before it arrives.

The tip is to treat the middle as the timer of a run. If Skinklet hides early in big waves, it needs levels, which raise the damage it can take first. Its evolved form, Skinkoon, gains range while hidden and is used in some alternatives on 2-10.
