Exeggulous devours both plants and other Pokémon ravenously, since it's always hungry. However, this isn't helpful for Exeggulous; it's only actually nourished by sunlight.

Since their two heads do not get along and compete with each other for food, they always eat too much. Originally from the tropics, Exeggulous's heads grow larger from exposure to strong sunlight.
