Plunger

A plunger is an item in Rayman Raving Rabbids. These are used by both Rayman and the Rabbids, mainly in the first-person shooting boss minigames where they are used as a weapon similar to guns.

When Rayman wins the boss minigame for each day, he is given a plunger as a reward which he figures out he can use to build a ladder up the wall of his cell and escape, and he needs 15 of them to reach the window.
