Koffing is a spherical Pokémon filled with toxic gasses. It has vacant eyes and a wide mouth that usually has two pointed teeth in the upper jaw. However, a full set of teeth has been seen in the anime. Below is face is a cream-colored skull-and-crossbones marking. Several crater-like protrusions, which usually release a yellowish gas, cover this Pokémon’s body. Its purple skin is very thin, and over inflation can cause it to explode.
