Mario has been betrayed by his own hat. In a video recorded by Twitter user DefinitivNichtSacha, a glitch in Super Mario Odyssey’s multiplayer mode allows players controlling Mario’s hat Cappy to kill Mario.
As seen in the video linked above, the glitch can be exploited by capturing a piranha plant like the one seen here in the game’s Luncheon Kingdom world. After feeding the plant a rock, the player controlling Cappy can kill both the plant and Mario by attacking the plant.
With the plant dead, Mario disappears from the screen, leaving only a floating Cappy on the screen. Players will then have to restart at a checkpoint flag to respawn Mario. See it for yourself in the tweet above if you’re looking for a way to troll your friends in Mario’s latest adventure.
Super Mario Odyssey launched October 27 for Nintendo Switch.
