Mr. Frosty is a recurring mini-boss in the Kirby series, first appearing in Kirby's Adventure. He is a dapper blue and white walrus with frosty breath that he uses to create ice blocks. Mr. Frosty wears black suspendered trousers that are always missing their seat exposing his blue butt when he turns around.
During battle, Mr. Frosty tosses ice blocks at Kirby that Kirby can inhale and spit back at him. He will also attempt to grab Kirby and put him in his mouth before spitting him out frozen. In some newer games he can even use his frost breath to fly for short periods of time. When inhaled, Mr. Frosty gives Kirby either the Ice or Freeze ability depending on the game.
Mr. Frosty appeared in Kirby Return to Dreamland in the mini-game named Mini Boss Challenge. The blue Mr. Frosty named Mr. Frosty EX appeared in Kirby Return to Dreamland in the mini-game named Mini Boss EX Challenge. The Mr. Frosty using Super Ability is named Super Mr. Frosty.
