“...Now for your next challenge. You must defeat me!”
When Mario and Luigi meet Hoohooros, the stone idol tests the brothers' ability to use the Spin Jump technique through a timed minigame, the goal of which is to get 10 Hoohoo Spirits within the time limit (30 seconds) without falling onto the ground. After completing the minigame, the brothers have to fight the stone guardian himself.
Hoohooros immediately creates pillars that he hides behind at the start of the battle, and will use them to fire lasers from one at the Bros. The brothers must destroy the pillar that he is not hiding beneath, then the one protecting Hoohooros. He will attempt to move to the other pillar, and becomes confused when it is not there. The brothers must quickly attack Hoohooros, as pillars will quickly begin to respawn. Hoohooros' only attack while exposed is to fire a laser beam that sweeps across the ground; the brothers must jump over it one at a time. After being defeated, the stone guardian relents and allows the brothers to journey to the summit.
Hoohooros apparently speaks the ancient language of Hooroglyphy.
