Badge Dojo · Rock 1-4

The middle lane holds just Drilleroo, and it is easy to underrate. It stands in row 2 of lane 2, one row behind the corner blockers, with empty cells all around it.

Drilleroo is a base-form specialist. It claws an area, and every so often a heavy blow throws enemies into a neighbouring row; the ones that cannot be moved get shredded instead. On this board that shove is useful, because a neighbouring row here means lane 1 or lane 3, where Snoozebo's thorns and Rubblet's beam are waiting. Drilleroo does not need to kill much. It just keeps the middle from becoming a straight road to the back.

Its weakness is that nobody covers it. With no healer on the board, it lives on its own health, so when it falls it is usually because a corner gave way first and enemies started arriving from more than one side.

An alternative layout replaces Drilleroo and stacks the lane instead: Joeyo, a base-form puncher, in row 1 and Gopher right behind it firing mud balls. That gives the middle a real blocker, at the cost of the shove.
