O' Berries are a fruit species native to Club Penguin Island. They have been seen in the wild growing on bushes, and are wild Puffles' main food source. They date back to medieval times. Different types have been seen, including Purple O' Berries and Golden O' Berry. They are the main ingredient in Puffle-Os, a popular type of Puffle Food. They have a spicy flavor, and aren't eaten by penguins, with the exception of PH.
