Toxic Mouth Pokémon
Toxicroak is a Poison / Fighting-type Pokémon, No. 454 in the National Pokédex, introduced in Generation 4 (Sinnoh region).

Toxicroak is a dark blue and teal biped, like a poison dart frog. Its yellow eyes have a snakelike pupil, a red vocal sac bulges under the chin, and red claws arm its hands.
It is swift, dodges well, and strengthens its poison by croaking: claws, stings, or a touch can poison. It lives near water and evolves from Croagunk.
It debuts with Saturn of Team Galactic and rivals Brock's Croagunk. Later, several angry Toxicroak chase Ash and his friends off a cliff.
It is based on the poison dart frog, and its claws recall the hairy frog and a ninja's wrist knives. Toxicroak may combine toxic and croak.
