Jyks

The Jyks are a group of enemies/traps in the 2008 videogame Super Smash Bros Brawl. They are non-sentient spike balls that move in a designated direction or stay in a specific area. Jyks are immune to all forms of damage and therefore can't be destroyed. This makes them one of the very few enemies that also acts as an environmental hazard in the game.
