From Creatures Wiki
Once Angry Nornito calms down, he leaves the Hatchery through the portal. It is currently unknown if he appears in the game again.
Even though he referred to himself as Angry Nornito, Nornito is actually unnamed by the game itself. Andrea Di Stefano of Fishing Cactus revealed that the name he refers to himself as is most likely a bug in the game.
Due to his popularity, his spirit has been put into a special item for Creatures Online - a chili.
