The longer a GEODUDE lives, the more its edges are chipped and worn away, making it more rounded in appearance. However, this POKéMON's heart will remain hard, craggy, and rough always.
Sapphire:
When GEODUDE sleeps deeply, it buries itself halfway into the ground. It will not awaken even if hikers step on it unwittingly. In the morning, this POKéMON rolls downhill in search of food.
Fire Red:
Its round form makes it easy to pick up. Some people have used them to hurl at each other in a snowball fight.
Leaf Green:
Found in fields and mountains. Mistaking them for boulders, people often step or trip on them.
