These items are found very early on, only after you get the Hammer. There is a lone tree located in Goomba Village. By smashing this tree, a Goomnut will fall and be picked up by Mario. These items are very weak, giving Mario only 3 points of FP.

Trivia

• Goomnuts are not featured in Paper Mario: The Thousand-Year Door but they are mentioned by Goombella as she says the Riverside Station smells like rotting Goomnuts when her area tattle is used in one room.
