Gooigi is an invaluable asset. Press the right stick to summon or dismiss him. Gooigi can walk through spikes, grates, and other hazards that Luigi cannot. He's also essential for solving many puzzles that require two characters. However, Gooigi is vulnerable to water and fire, so be mindful of his surroundings. Use him to reach inaccessible areas, activate switches simultaneously, or even distract ghosts while Luigi attacks.
