Horns & Teeth
Vespires can have horns granted by the various potions (dragon, uni, etc.). In addition to this, if they are a cherub hybrid, they are able to have cherub horns at the legendary level.
Since vespires have beaklike mouths, their "teeth" are an extended part of the beak's edge and are not true teeth as such. They can be either the same or different color as the rest of the jaw.
