Kuzzle

Kuzzle is an elderly Koopa Troopa found during the events of Mario & Luigi: Bowser's Inside Story. He enjoys doing puzzles, and was a former Star Sage before Bowser stole the Star Vaccine that he was supposed to guard. He explains to Mario and Luigi about where the Attack Pieces are, and also lost his furniture to enemies. Mario and Luigi go find the puzzle sacks that the furniture is placed in, getting three beans after finding them and placing them together.

Trivia

 * Kuzzle enjoys doing puzzles. His name rhymes with puzzle.
 * Out of all three Star Sages, Kuzzle is the only one that is not seen battling, though he probably did fight Bowser for protection of the Star Vaccine.
