In the Pink

Ash and friends are caught in a whirlpool and swept to an unexplored island where all the Pokémon are pink. It's Pinkan Island, a Pokémon refuge where the Pokémon's diet of Pinkan Berries causes their unique coloration. But the Pokémon aren't all as sweet as they look. Our heroes cross paths with an enraged Nidoking, and end up cornered under a cliff.
