Thin Ice is a game located in the Dance Lounge that is styled around a classic arcade game. In it, the player must guide a Black Puffle that is on fire (probably by the effects of O' Berries) through a maze covered in ice, melting as many ice squares as they possibly can along the way, while collecting coin bags to earn additional coins and pushing blocks to their correct positions.
There are no lives, and levels can be passed without fully completing them. There are 19 levels in total. At the end, the puffle smiles, is unhappy, or is angry depending on how well you did in the game.
