“CUSH SAYS CUSH, SHAWN SAYS SHAWN, THEN SAY CUSH AND SHAWN!”
During the events of the game, Mario and Luigi travel to Mount Pajamaja to track down Bowser and Antasma. While scaling the mountain, he sees a barrier that not even their guides, the Massifs, can break. Dreambert suggests to find two Mega Pi'illos who are trapped in Nightmare Chunks. Cush happens to be one of them, along with his relative Shawn. Once both are free, they sing a song and destroy the barrier with their sheer strength. Mario and co. move on towards the summit, thanking Cush and Shawn for helping them.
