When Squash spots a zombie in an area near him, he will jump up high before smashing the target, dealing 1800 damage per shot worth of damage to any enemy on the tile Squash lands on.
Squash is a recurring character within the Plants vs. Zombies franchise. Squash squashes zombies he spots, either a tile ahead of him or a tile behind him, dealing massive damage to all zombies on that tile, thus acting like an instant Potato Mine with better range.
