Whacka
Whackas are blue mole-like creatures that live on the west side of Mt. Rugged, near the shore of Keelhaul Key, and near Downtown of Crag. Hitting one on the head with a Hammer will make a Whacka's Bump, an edible and valuable item, appear. However, this causes internal injuries to the Whacka. If they are hit too many times or blown up by bombette, they will die, releasing a few coins. Since their bumps are so valuable, Whackas are an endangered species and should be treated with care. According to Wonky, there is only one Whacka left in the world. This fact is proven false, however, in Mario Party 6, on the Snowflake Lake board, Whackas can be seen popping up out of the snow.
When Whacka disappears in Super Paper Mario, a cave woman appears where Whacka popped out. She claims that the Whacka was hers.
At one point, the Whacka on Mt. Rugged sends Parakarry a letter stating he one day dreams of flying. The Whacka that appears in Super Paper Mario's Catch Card can be obtained by collecting three hundred shop points.

Trivia
- Whacka's name is derived from the popular arcade game "Whack-a-Mole" where the player has to hit a mole that comes out from a hole.
- Whacka's appearance is very similar to Diglett, a Mole-type Pokémon. Like Diglett, Whacka's body under the soil is completely unknown and never seen.
- Whacka is possibly a reference to Super Scope 6, a 6-in-1 game bundled with the Super Scope which included a game called Mole Patrol. The game's point system was similar to a "Whack-a-Mole" game, and the goal was to shoot evil blue moles. Whacka is indeed a blue mole-like creature.
