Pokio

Pokios are hummingbird-like enemies found in Bowser's Kingdom in Super Mario Odyssey. They wander around and poke Mario with their beaks when he approaches them. To capture them you first knock off the samurai helmet that they wear. Once captured, you can poke enemies with your beak. If you poke at a wall, you can cling onto it and fling yourself upwards. This is useful for climbing up walls and is necessary to beat RoboBrood.
