Hoohoo Mountain (ウフマウンテン Ufu Mountain?) is a large mountain north of Beanbean Kingdom in Mario & Luigi: Superstar Saga. When Mario and Luigi first came here, they mistaken the villains who kidnapped Prince Peasley for helpers.
Hoohoo Mountain is an ancient rocky mountain with Hooroglyphs engraved on its walls, which chronicled countless jokes. There are Watering Holes that can be used to extinguish Fire Statues. The extinguished Fire Statues absorbs the vapor to the Mask, which produces a whirlwind. On top of the mountain is a telescope that allows anyone to view the Beanbean Kingdom.
