Bolum is a robotic dome-shaped enemy with small legs on a platform. In Kirby Super Star and its remake, its dome is colored red, and in Kirby: Planet Robobot, its dome is pink. In both Kirby Super Star and Kirby Super Star Ultra, it had two spherical purple appendages, and in Kirby: Planet Robobot, it now has four cylinder-shaped purple appendages.

Kirby Super Star / Kirby Super Star Ultra
Bolums appear alongside Patas and Dakugas inside the Galactic Nova, often appearing in groups, albeit the minor difference is that it walks on both the ceiling and the floor, and fires smaller projectiles Kirby's Starship in an attempt to defeat the hero.

Kirby: Planet Robobot
Bolums appear once again in this game, albeit the only difference is they appear inside Star Dream Soul OS alongside Patas and Dakugas, summoned through its Supervisor Call attack. This time, Bolum provides the Bomb ability.
