“Oh, it's Mario!! See this fine club I have? I'm gonna introduce you to it. Club...meet Mario!!!”
Clubbas are large, burly but lazy creatures who are often shown to work for Bowser as soldiers; though some Clubbas have shown to be neutral characters. A Clubba's trademarks is its spiked mace and tendency to sleep a lot. They closely resemble the smaller Spikes, and their Japanese name Gabon Hei (lit. "Gabon Soldier") implies that they are directly related to them, as Spikes are known as Gabon in Japanese. Clubbas only appear in the Paper Mario series.
The first Clubbas appeared in Paper Mario, where they were commonly seen guards in the castle of Tubba Blubba, himself a monstrous Clubba. Only a few of Tubba Blubba's Clubba henchmen actively guarded the castle, and if Mario so wished, he could simply sneak by sleeping Clubbas, which would only wake if they sensed a quick movement. If the player chooses a Clubba as one of the things Mario fears in a Princess Peach intermission, Kammy Koopa will summon one to guard a Treasure Chest in the Shy Guy's Toy Box. Later in Paper Mario, a single Clubba appears as a sleeping guard in Princess Peach's Castle; sleeping while it was supposed to be guarding a door in the castle. This Clubba could have its appearance copied by Princess Peach and her Sneaky Parasol, making a Clubba, complete with its mace, playable in a sense.
Paper Mario: The Thousand-Year Door
Super Paper Mario
The most recent appearance of Clubbas has been Super Paper Mario, where they appear in all the surface areas of the Gap of Crag. They have very high HP in this game. Once more, they were often found napping and could be avoided by the player's character. A Clubba can also be fought against in Castle Bleck as an optional enemy, like in Paper Mario. There was also a very brief mentioning of Tubba Blubba, by Francis. According to him, Tubba Blubba stars in his own TV series called The Blubbening. Super Paper Mario is notable for being the only game in the series that does not feature a Clubba as a boss in the game's third chapter.
After completing Chapter 3, all enemies, including Clubbas, abandon Tubba Blubba's Castle except for one in the first floor east wing. He apparently fell asleep and got left behind and when talked to, he will wake up and realize this before falling asleep again. Being a regular NPC at this point, he can be Tattled on in the field.
