Bo is an enemy in Kirby 64: The Crystal Shards that gives no ability when inhaled. The appear in a mid-boss fight against Pupa in Stage 3 of Shiver Star, and are used to damage it.

Physical Appearance

Bos resemble small black spheres with rectangular white eyes, and they are surrounded by a blue aura.


Bos do not actively attack Kirby, but instead float around aimlessly.  They are often found in groups, likely because they are mostly harmless and easily defeated.


  • If Bo is held above Kirby's head, it will immediately disappear and do nothing.
  • Magoo, an enemy found at Neo Star's volcano, is a fiery version of Bo.
  • In some dark stages in Kirby: Canvas Curse, tiny blob-like shadow creatures move around on the ground. They have round, purple bodies, silver eyes, and vaguely resemble a smaller version Bo.
  • There's a similar enemy to Bo in The Legend of Zelda: Majora's Mask called Boe. They both look and act similarly, but unlike Bo, Boes leap onto Link.
  • They look similar to Mariel, except they have no legs.
