Grotle's claws glow white, then grow longer. It then runs quickly at the opponent and hits it with one of its claws, or slams into it with great force. It can also jump extremely high when using the attack, or Grotle's claws glow white and extend, and it gets on its hind legs and slams its front ones into the ground. A giant mountain then protrudes from the ground under the opponent. Grotle runs up the side of the mountain and slams into the opponent with great force.
Torterra's claws glow white and then grow longer. It then gets onto its hind legs and slams its front ones into the ground. The ground separates and protrudes from the ground under the opponent. Torterra then runs up the side of the protruded ground and slams into the opponent. When Torterra is defeated, the ground forms back to the way it was.
In Pokémon HeartGold and SoulSilver, Rock Climb can be obtained and used as an HM, after Viridian City Gym Leader Blue has been defeated. This makes Rock Climb the only HM that requires a Gym Badge outside of the starting region in order to be used.
Rock Climb was the last HM move to be introduced.
Some of the Pokémon that can learn Rock Climb, such as Granbull, appear to lack the physique required to climb walls while carrying a human.
