Fish (item)

The Fish is a pet-summoning item that spawns a Penguin to follow the player around. If the player moves too far away, the pet will fly after them. The Fish is found randomly inside Frozen Chests in the Ice biome, and dropped from and  obtained via fishing in the Ice biome. When the player is flying or far enough away, the Penguin will generate Hermes Boots sparks and fly to catch up to the player.

Trivia

 * The Baby Penguin looks identical to the penguin inside the Penguin Cage.
 * The Baby Penguin's use of a jetpack in its flying animation is a reference to Sgt. Byrd from the Spyro the Dragon franchise.
