Ice Age

Ice Age (also known as Ice Age II) is an unlicensed game for the Game Boy Color released in 2002. The gameplay is similar to the Klonoa series of platform games. The game is loosely based on the movie Ice Age, and you play as Sid the Sloth. The player has to reach the end of the stage by grabbing enemies to use for double jumping and attacking. Each stage has crystals to collect, which are shown along with the total amount in that stage in the bottom HUD. Each area has three stages to complete, with a boss at the end of every third stage, and can be revisited after completion.
