Wailord

The biggest of all Pokémon. It can dive to a depth of almost 10,000 feet on only one breath.

Poke-BODY — Sleeping Pulse: As long as Wailord remains Asleep between turns, remove 1 damage counter from Wailord.

Sink Deep (60): If Wailord has any damage counters on it, Wailord is now Asleep.
