Buboo is a mini-boss that appears in Kirby Squeak Squad. He is a being concealed inside a barrier of bubbles and floats around shooting bubbles (some of which contain Waddle Dees) at Kirby. After taking enough damage, his barrier will dissipate, revealing his true form: a small, weak, crab-like creature. With his cover blown, Buboo will scurry around hastily on the ground, vigorously throwing out bubbles every which way. Buboo is extremely fast on the ground, and is only matched by the speed of a running Golden Waddle Dee. When the player defeats him, Kirby has the option of inhaling him for the Bubble copy ability.
He could be related to other aquatic crustaceans such as Kany and Coner.
Buboo is a timid creature that hides in an immense cloak of everlasting bubbles. He uses his constantly-regenerating bubble blockade as means of flying, as Buboo drops to the ground right after all the bubbles are gone. Buboo replenishes his barrier by spitting out more bubbles.
Having lost his bubble barrier, the player can see Buboo for what he really is. He is a bright red, parasite-like crab with small back eyes, two small pincers, and six small horns.
