Easy rat trapping:
This may be done 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 useful in areas where Krusty must build stairs for the rats to climb in order to reach the trap.
