From WiKirby, your independent source of Kirby knowledge.
Boomer is an enemy from Kirby's Dream Land, found only in the Bubbly Clouds stage. It is found only in Extra Game - replacing Sir Kibble - and behaves in much the same way. Boomer's name is derived from an abridged form of the word 'boomerang', after its preferred weapon. Boomer is worth 1000 points when defeated.
Appearance and behavior
Boomer is a vaguely humanoid figure who resembles Poppy Bros. Jr. greatly, though it wears a lighter set of clothes and does not bear a permanent grin on its face, instead only having a pair of slits for eyes. Its hands and feet are the same color as its face, implying that it may be barefoot.
Boomer stays in one place or patrols an area, tossing boomerangs at Kirby. It tosses them more frequently than Sir Kibble, and tosses two at a time.
