Clay's Palpitoad is a water/ground-type Pokémon owned by Clay.
He used it to battle Ash's Oshawott and Snivy. It defeated Ash's Oshawott by separating it from its schalchop with Sludge Bomb and then knocked it out with Rock Smash. Despite his supereffective Sludge Bomb, it stood no chance against Ash's Snivy, since it was hit with Attract first. It was able to endure Vine Whip and Leaf Blade before falling to a powerful Leaf Storm.
