Multibounce

Multibounce is a badge in Paper Mario and Paper Mario: The Thousand-Year Door. In Paper Mario, it can be bought from Rowf and Rhuff's badge shop after chapter one for seventy-five coins. In Paper Mario: The Thousand-Year Door, it can be found at Shhwonk Fortress, inside a red ? Block in the Fortress' sewers, obtained at Pianta Parlor after getting the Silver Card for fifty Pianta Tokens, or dropped by Paragoombas, Paragloombas, Dark Paratroopas, Parabuzzies, Spiky Parabuzzies, Swoopulas, and Swampires. If equipped by Mario, it lets him perform a Multibounce move that costs two FP; it is a jump attack that hits all enemies one after the other, starting from the one at the front, if the action command is timed correctly. Messing up the action command stops the attack at whichever enemy Mario had reached. Equipping multiple copies of the badge increases the damage it does while also incrementally increasing the FP it costs.
