Booler

Booler, also known as Bumpin' Boo, is a mischievous ghost that appears exclusively in Castle Lololo from Kirby's Dream Land. They float eerily chasing Kirby or just drift around in set patterns. When Booler floats, it wags its tail around. Gaspar replaces Booler in the Extra mode.

Booler later appeared as an enemy in Kirby's Pinball Land (in which they behave the same way they did in Kirby's Dream Land) and then in Kirby Tilt 'n' Tumble. In Tilt 'n' Tumble they don't stick out their tongues out but now have a tendency to get angry if Kirby bothers them.

To date, Kirby's Dream Land is the only platformer that Booler appears in. The rest of its appearances are all in early spin-off titles.

Physical Appearance
Booler is a nearly-transparent specter. He glows with an eerie blue glow and has a wicked smile on his face. Booler has a long, wispy tail and often bears his large, red tongue in a childish manner. Booler is also shown to be trailed by a paranormal flame; a common trait of many stereotypical spirits.

Trivia

 * Booler shares many similar traits with Boo, an enemy in the Mario series.
