Stunky are small, mammalian (in particular, skunk-like) Pokémon that are dark purple with a white stripe running down their backs and cream underbellies. Their faces are large and rounded, with a narrow red nose, red-rimmed eyes, and two pairs of somewhat "V"-shaped cream-colored whiskers on the sides of its face. Feline-like features (including the ears) may relate to skunks being called polecats.
