Ultra-sun: It climbs up cliffs as it heads toward the peak of a mountain. As soon as it reaches the summit, it rolls back down the way it came.Moon: This slow-footed Pokémon moves by curling up and rolling instead of walking. With enough momentum, its speed can exceed 60 mph.Alpha-sapphire: Rocks are Graveler’s favorite food. This Pokémon will climb a mountain from the base to the summit, crunchingly feasting on rocks all the while. Upon reaching the peak, it rolls back down to the bottom.
Prof. Lotus' Notes: Graveler's Japanese name is ゴローン (Goron), and avid Legend of Zelda fans would find that the rock species share the same name. This is because this is a play on words, ゴロゴローン (Goro Goron) is the onomatopoeia of rocks falling, a trait both of them share. In the original Red and Blue version of the game, the sprite incorrectly had 4 limbs visible instead of 6. This was fixed in the Yellow version.
