With balloon and Moai Pokémon out of the way, it's a little surprising that they're just now getting to skunks. Stunky's face is suspiciously butt-shaped, reinforcing its fetid appearance. Definitely more interesting than Glameow, Stunky's Poison type protects it from Fighting Pokémon, the usual foil to Darks, while the Darkness protects it from Psychic's anti-Poison potential, leaving it open to Ground attacks. Like all poisonous creatures, Stunky is popular with the local villainry, and can only be caught in the wild in Pokémon Diamond.

Evolves into Skuntank at level 34.
