It still frustrates me! Aromatisse! "Its scent is so overpowering that, unless a Trainer happens to really enjoy the smell, he or she will have a hard time walking alongside it." It uses odors (Like Skuntank and GarbODOR, the smelliest Pokemon) to battle! How is it not Poison/Fairy?!
you can't enjoy the smell of poison, you die.
thus it is not poisonous, just annoying since some can enjoy the smell
