Il Piantissimo

Il Piantissimo is a human whom is desguised as a Pianta. It is, though, unknown why he does it. He first appeared in the game Super Mario Sunshine for the Gamecube. In the game, he offered to give you a Shine Sprite if you beat him in a race. You race him 3 diffrent times in 3 diffrent levels- Gelato Beach, Noki Bay, and Pianta Village. Each race gets more and more challanging. He resembles Koopa the Quick from Super Mario 64 whom would give you a star if you beat him to a certain destination.

If you beat Super Mario Sunshine without collecting all the stars, you'll see Il Piantissimo looking at the paint-brush that Bowser Jr. used to turn into Shadow Mario. It's unknown why this is here, it is possible that there getting you ready for a sequal, but it's also possible that its there for no reason.
