“Whack-OOOWWWWWWW!!! Don't hit me!”
Whackas are sentient, rare, blue mole-like creatures in the Paper Mario series. Their name is derived from the popular arcade game "Whack-a-Mole". Hitting one on the head with a Hammer, Kooper or Koops's shell, or jumping on it makes a Whacka Bump appear. However, if they are attacked eight times, they run away, releasing a few coins.
Whackas first appear in Paper Mario where only one lives on the west side of Mt. Rugged. Due to the Whacka's only appearance in the game, Russ T. attributes their rarity to the hunting of their bumps. At one point, the Whacka on Mt. Rugged sends Parakarry a letter stating he one day dreams of flying. Whacka is one of the few friendly characters that get hurt when hit in Paper Mario.
Whackas reappear in Paper Mario: The Thousand-Year Door near the shore of Keelhaul Key, behaving alike as their incarnation in Paper Mario. According to Wonky, there is only one Whacka left in the world, which confirms Russ T.'s rarity of them.
Whackas reappear in Super Paper Mario near Downtown of Crag, also behaving identically as their earlier incarnations. When the Whacka disappears in Super Paper Mario, a female Cragnon named Norite appears where Whacka once popped out, who claims that the Whacka was her friend. The Whacka also appears as a Catch Card that can be obtained by collecting three hundred shop points. There is also a Sammer Guy by the name of Wrath of Whacka in the game, who says he hopes to avenge the smitten Whackas of the dimensions.
