Il Piantissimo is a dark-skinned man disguised as a Pianta that the player must race in Super Mario Sunshine. He could be raced in Gelato Beach, Noki Bay, and Pianta Village.
Piantissimo is very overconfident, and finds himself superior to others. According to various locals at Pianta Village, he is considered a rogue, a creep, and not related to the Piantas. This could show that due to his attitude, he is left alone and barely challenged, adding to his superior personality with no one to go against it.
Once the game is beaten with one hundred and nineteen Shine Sprites or less, the ending screen will show Il Piantissimo finding Bowser Jr.'s Magic Paintbrush. This alludes to the possibility that he took it. He is confirmed to make an appearance in the upcoming game, Piranha Planter.
In the game Bowser Jr's Army, he covers himself in the paintbrushes grafitti and becomes Grafitti mario.Looking like Mario he goes around and commits crimes and can even paint him self to look exactly like Mario.He also races/battles mario.
