Fish are pickups in Avalanche. They have large, round bodies, with very small tails. The back part of their body is dark orange, while their head is lighter. On their head is a large, red eye. Every fish collected adds 50 points to the player's score. They float in the air, usually over jumps.
In the game's ending, the penguin is seen feeding her babies with fish.
They are very similar to the fish in Rockitty, as they both can grant 50 points, and they are similar in appearance.
