Instructions
Complete challenges to collect Jinjo Tokens. There are several challenges to find throughout the entire game, each of which has its own required task. For example, "Red Jinjo Speed" in the beginning grassy area requires you to exceed a certain speed, rewarding you with one token.
Head to the Jinjo Bingo building, marked on your in-game map, once you have nine Jinjo Tokens. Place one token on each square in the ninth column. Filling out this column rewards you with a pair of Folding Wings.
Play through the game as normal until you reach the Jiggoseum Doors, which are accessible in the fifth act of the game.
Jump onto the lower rooftop, allowing you to jump onto the middle rooftop of the Jiggoseum Doors. Break open the crate to get the second pair of Folding Wings.
