The Growshroom is a large half-buried mushroom found in the Caverns of Chaos; it is worth 50 Pokos. The name is a reference to the Mushroom of the Mario series, and this reference is continued into the entry in Olimar's Journal and the Sales Pitch for the treasure as being able to increase one's size.
