Room-shroom(Whee23PVZ)

room-shroom is a plant that allows you to plant two plants on the same tile. when you put a room-shroom on an already occupied tile, that plant will be in the bottom part of the room-shroom. you can plant another plant on top of the room-shroom, so you can have two plants on the same tile. having a room-shroom fully occupied is sort of like merging the two plants, for example putting a wall-nut and a peashooter in a room-shroom would basically make a pea-nut. zombies will always eat the inside plant first, and then they will eat the room-shroom itself, not the plant on top (however, when the room-shroom is eaten the plant on top will also dissapear.), so putting a defensive plant on top is rather useless.
