|“||Each time the pinball hits Mr. Frosty, one of the letters in the word "FROSTY" lights up. When the word has been completely illuminated, Mr. Frosty can catch Kirby and start to spin. Using the A Button, stop Mr. Frosty's spin and shoot Kirby in the desired direction.”|

Inhaling him grants Kirby either the Ice or Freeze Copy Ability, depending on the game. Being a creature of ice, abilities with the Fire element do much more damage in battle and can defeat him more quickly.
Kirby's Adventure marked Mr. Frosty's first appearance.
Mr. Frosty uses two attacks: charging at Kirby, and preparing and tossing a block of ice at him. In Orange Ocean, there is a room where two Mr. Frostys are fought. In this game, Kirby gets the Freeze ability from Mr. Frosty.
In this game, Mr. Frosty resides in Poppy Brothers' Land. He stands in the middle of the screen on the bottom stage, with the name 'FROSTY' written below him. He poses no threat to Kirby, but instead helps the hero. Each time Kirby hits him, a letter of his name will light up; once his full name his lit up, Kirby can bound into his arms. As Mr. Frosty swings him around, the player can launch in the direction Mr. Frosty is facing by pressing A. This serves as a helpful way to get onto the middle stage.
Oddly, every time Kirby hits him, his overalls fall down, exposing his belly button. He quickly pulls them back up after being hit.
Mr. Frosty appears in this game similarly as he had in in Kirby's Adventure, except that when inhaled, Kirby is granted the Ice ability instead of the Freeze ability due to the replacement of Freeze with Ice in this game.
Mr. Frosty appears in the sixth stage on the fourth room, guarding the Warp Star. After Kirby gets onto the star, he has to fight Mr. Frosty.
Mr. Frosty reappears with the same tactics as he had in Kirby's Dream Land 2, with one exception: he gains the ability to grab Kirby, stuff him into his mouth, and spit him out, dealing damage. He still gives Ice when inhaled. In this game, however, Mr. Frosty is more spontaneous in his movements, making him slightly harder to defeat. Mr. Frosty has 100 hit points, making him one of the weaker mid-bosses. For the first time in the series, he is weak to Fire-based attacks.
Mr. Frosty was slated to appear in the Nintendo 64 version of Kirby Air Ride. Whether he was playable or not he was not revealed, due to the cancellation of the game. He does not appear in the GameCube version.
In Kirby & The Amazing Mirror, Mr. Frosty's name was mistranslated/misspelled as Mr. Flosty. He is still mostly the same as he was in Kirby: Nightmare in Dream Land. This time however, he will sometimes throw a huge block of ice that can only be inhaled with a super inhale. Also, Mr. Frosty retains his swallow-and-spit technique from Kirby Super Star. Mr. Frosty still gives Ice when inhaled.
Mr. Frosty's tactics and appearance have not changed since Kirby & The Amazing Mirror.
Mr. Frosty does not appear in the main game. However, he appears in the sub-game Kirby Quest, in rounds 26 and 38. He is accompanied by two Oohroos and two Ice Noserunts, respectively. He has the same sprites and attacks as in Kirby Super Star Ultra, with a slight change in color.
Mr. Frosty again appears as a mid-boss in this game. While he uses some of the same old attacks, he has new techniques such as one resembling the Ice Sprinkle attack. He is again weak to fire-based attacks.
In the Anime
Mr. Frosty also has a small cameo appearance in the anime episode Cowardly Creature.
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. However, 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." Mr. Frosty is one of the few monsters to be shown in the training school. He, along with Yaban, is a member of the Flower Class, which is the weakest of the whole school, which is ironic seeing that he's the only mid-boss in the whole school (excluding Jukid, who only appears in only two games, who is also only one level above Mr. Frosty). He is shown riding precariously on top of a unicycle.
- Although Mr. Frosty had no physical appearances in Kirby: Canvas Curse, he made a small cameo in one of the paintings painted by Paint Roller in the sub-game Paint Panic.
- Mr. Frosty's earlier sprites bear some resemblance to Roly-Poly but no evidence supports any form of relationship between the two.
