Yuki

Yuki is a mid-boss that appeared in Kirby's Dream Land 3, who replaces Mr. Frosty for said game. Defeating Yuki yields the Ice ability when inhaled.

Physical appearance
Yuki resembles a snowman, or a big pile of snow with 2 small black eyes and a mouth. Wappa somehow resembles this mid-boss with a similar build and yields the same ability.

Kirby's Dream Land 3
Yuki appears in this game as one of the mid-bosses Kirby must face. His attack plan involves jumping around (roughly performing 3 large jumps), throwing snow balls, including his own head that Kirby must inhale in order to defeat him. When he loses his head temporarily for a few seconds, he stays in one place until his head grows back.
