Stunky
The Skunk Pokémon
Type: Poison/Dark
Official Registration #: 434
Entry: A small, woodland pokémon known for its powerful defense mechanism. When threatened, rather than attacking using traditional pokémon moves, stunky will turn its hindquarters to face its attacker, lift its tail, and spray a potent musk to confound and drive away the offending creature. As an important side note, Sinnohan folk remedies prescribe bathing in tomato juice in order to remove the smell. The writer fully encourages stunky victims to do this, not because of its effectiveness (it is, in fact, not even remotely effective) but instead because bathing in tomato juice is strangely good for the skin.
Skuntank
The Skunk Pokémon
Type: Poison/Dark
Official Registration #: 435
Entry: The evolved form of stunky, by battle experience. Skuntank is basically a larger, more dangerous stunky. What makes it so dangerous are a combination of factors, namely its hotter temper and the fact that the range of its spray can reach up to 160 feet. Word of advice, should you ever encounter a wild skuntank: one quart hydrogen peroxide, quarter cup baking soda, and two teaspoons of dish soap. Mix and use the way you would everyday body soap and shampoo. You are very welcome.
