Kuzzle

Kuzzle is an elderly Koopa Troopa encountered during the events of Mario & Luigi: Bowser's Inside Story. He enjoys doing puzzles, to which his name is a reference, substituting the "p" for a "K", to reflect his species. He has a red shell and unlike other Koopas, blue skin, which may be a reference to Squirtle from the Pokémon video game series. Kuzzle says that he never cared about his looks, only his mind and prides himself on being able to quickly solve puzzles.

Kuzzle is a Star Sage, but unlike the other two, interacting with him is optional, as his Star Cure had been stolen by Bowser some time before the events of the game. If spoken to, Kuzzle will tell Mario and Luigi about how Bowser barged into his house in a rage one day, but Kuzzle's attempts to placate him with a puzzle just angers him more and he trashes the house before leaving with the Star Cure. Some time after that, Kuzzle inadvertently turned all his furniture into puzzles, and the Puzzle Sacks the pieces were held in scattered across Plack Beach, where his house is located. Mario and Luigi go find the Puzzle Sacks, receiving three beans (a Power Bean, a HP bean, and a Special Bean) after finding each of them and placing them together. If all of the furniture is put together, the Mario Bros. will receive 30 (10 of each of the above) beans.
