Badge Dojo · Rock 1-5

Rubblet is the right side's wall, and unlike Snoozebo on the left it has no way to heal. From row 1 of lane 3 it fires a hot blue beam that damages an area, so groups that bunch up against it take the beam together.

That difference decides which corner breaks first. Snoozebo recovers while it fights; Rubblet only loses health. On longer waves the right side is usually the first to go, and once Rubblet falls Taptail in row 4 is left exposed.

Rubblet is also the start of a line that matters later. Its evolved form, Cobbledon, fires beams that split across a wide area and becomes a regular on the later Rock Dojo boards. Levels put into it now are not wasted.

An alternative layout for this run swaps the corners: Rubblet goes to row 1 of lane 1 with Rockhog two rows behind it, and Gibber stands in row 1 of lane 3 instead. Rubblet keeps a front-row cell in both versions, which tells you how much the board relies on it.

If lane 3 is where you lose, level Rubblet before touching anything else.
