Yes, Grumpig doesn't to jump all the time, fortunately.
Elgyem's Black dex: It uses its strong psychic power to squeeze its opponent’s brain, causing unendurable headaches.

Edit: Stunfisk, too.
Black: Its skin is very hard, so it is unhurt even if stepped on by sumo wrestlers. It smiles when transmitting electricity.
White: It conceals itself in the mud of the seashore. Then it waits. When prey touch it, it delivers a jolt of electricity.
BW2: When its opponent can’t be paralyzed, it contorts itself with unexpected speed and flops away.
So, it waits and traps then shocks foes while smiling maniacally, then storms away when it can't do so?
