O' Berries are a fruit species. They have been seen in the wild growing on bushes, and are wild Puffles' main food source. They are the main ingredient in Puffle-O's, a popular type of Puffle Food. They have a spicy flavor, and aren't eaten by penguins, with the exception of PH. In G's Secret Mission and Questions for the Crab, O' Berries are used to complete the mission.
