Kuzzler

Kuzzler is a old Koopa who lives on Plack Beach in Mario & Luigi: Bowser's Inside Story. Kuzzler is a master puzzler who has you go find puzzle sacks found around Plack Beach to complete them to get different Beans. When you first meet Kuzzler, he offers to give you a puzzle to do. If you complete the puzzle, Kuzzler will give you 10 Attack Pieces for the Special Attack, Spin Pipe. Then Kuzzler will ask you to find 4 puzzle sacks around Plack Beach to restore all the furniture in his house. If you find a puzzle sack and take it to Kuzzler, you will have to do a puzzle to restore the furniture within the puzzle. If you find and complete all the puzzles, Kuzzler will give you some Beans.

Later in the game you will find out the Kuzzler was one of the former Sages but the Star Cure know lies with a different Sage on top of a mountain in Plack Beach.
