Whacka Bump

Whacka's Bump is an item in the Paper Mario series. It restores 25 HP and 25 FP. It can be sold for up to 64 coins.

They are obtained by whacking a Whacka on the head with a Hammer. But be careful! After eight hits, Whacka will die and the player will be unable to get any more Whacka's Bumps.

Whackas and Whacka's Bumps also appear in Paper Mario: The Thousand-Year Door on Keelhaul Key. Once again, eight hits will KO the Whacka forever.

Whacka's Bump is also available in Super Paper Mario, in which it heals 30 HP. At the arcade, it can be traded for 300 Flipside Tokens. Whacka can also be found in Chapter 5-1. In the first part of the level, go to the far right wall. Use Dottie to shrink and use Mario to flip to 3D. Whacka resides inside the hole.
