Fishing Boo

Fishin' Boos are the spirits of Fishin' Lakitu found in Super Mario World and Super Princess Peach. They carry a fishing rod and ride a Lakitu's Cloud, much like the living variety. However, instead of a 1-Up Mushroom, Fishin' Boos carry a flame and follow Mario or Luigi in a way that makes it hard for them to Jump. A Fishin' Boo has the same immunities as a normal Boo and therefore cannot be jumped on.

Fishin' Boos also make an appearance in Super Princess Peach. A calmer variety called Calm Fishin' Boo also appears. Only Rage destroys them.

Trivia

 * The fishin' boo was going to appear in New Super Mario Bros. Wii but was scrapped.
