Squid Fit

Bowser riding the Squid Fit.

Squid Fit, also known as Squid Diet, is a wooden raft that can be used by Bowser to cross the water to reach some other islands. He can use it by going onto the wooden raft, then punch a wall the closest to him to sail the opposite way. Mario and Luigi are unable to use the Squid Fit, due to not being able to punch in this game. It was mentioned by a Toad in Toad Town who said that Mario and Luigi didn't have to use it because they're fit enough.
