This is one of the minigames in Rayman Raving Rabbids. The mini-game game consists of pulling worms out of a Rabbids' mouth. If too late, the worms go back into the rabbids mouth, and hurt the rabbid. If too many worms get into the rabbids' mouth, the mini-game ends.
In Part 2 of the mini game, the rabbid emits bad breath and changes the position of his mouth.
