In any room where Krusty has at least two moveable
blocks, position the first block near a wall. Wait until
the rats have crossed and are between the wall and the
block. While standing on top of the first block, release
the block that Krusty is carrying and trap the rats. If the
area where the rats are trapped is only as wide as one
block, all the rats in that space will be compressed into a
single rat. This is especially helpful in areas where Krusty
must build stairs for the rats to climb in order to reach the trap.
