A Muskog is a frog-like creature that burps stinky gas when frightened. During Book 1: Keeper of the Lost Cities, Stina puts a Muskog in Dex's locker as revenge for making her bald with a potion. Keefe also admits to kissing a Muskog once in the past. He admits it in book 4: Neverseen, it in the healing tent of Exillium. This species is once referenced in an insult by Stina Heks who claimed that even a Muskog could beat Dex in splotching.
