Bombchu

A Bombchu is an item originating from The Legend of Zelda franchise. It appears as an item in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate. A fighter can activate a Bombchu by throwing it, and in doing so, the Bombchu continues moving in one direction in a non-stop path, going over obstacles, walls and even ceilings or under the stage. If a fighter touches the traveling Bombchu, it explodes on impact, damaging them. Bombchus can be destroyed by lava and other attacks.
