Boomer

Boomer is an enemy from Kirby's Dream Land that replaces Sir Kibble in the Extra mode. Their boomerangs are faster than that of their weaker counterparts and are much more preemptive, being able to throw two at a time. He is an elf-like foe wearing a small pink shirt and a tiny floppy hat. His name is derived from the type of projectile that he throws.

While Boomer hasn't appeared in any games since Kirby's Dream Land, Poppy Bros. Jr. and Perot are similar enemies and have the ability to throw boomerangs much like this classic enemy.

Physical Appearance
Boomer is a small elf wearing red clothing. He has a round head, an oval-shaped body and walks around barefoot. His body is a cream-colored yellow. He also wields a blue boomerang with light-blue tips. This enemy may be the inspiration for Poppy Bros. Jr., who looks exactly the same and can throw boomerangs.

In the anime, his skin appears slightly paler and his clothes are a darker shade of red.

In the Anime
Boomer has a small cameo appearance in the anime episode "Cowardly Creature". Other members include Mr. Frosty, Yaban, Whiskers, Jukid, Dogon, Poppy Bros. Jr., and Hot Head.

When Phan Phan escapes, Customer Service turns to Dedede to help return him. Dedede is angry at him, and tells him that he should be ashamed for letting him escape. But Customer Service says that he wasn't in his care at the time. He goes on to explain that he was at the "Monster Training School". Boomer is one of the few monsters to be shown in the training school. He, along with Dogon, is a member of the Moon Class, which is the second strongest of the whole school, and is surpassed only by the Snow Class. Instead of throwing a boomerang, he balances on a rolling barrel (much like Poppy Bros Jr. could ride on apples). It is not known what becomes of him after Nightmare is destroyed, neither is it known if he even finishes training school and becomes a full-fledged monster by the end of the series.

Unlike many of the other characters of the anime, Boomer has the exact same design that he did in the games.
