After the fairy king grants him the feline body he's always longed for, Tobi works to uphold his end of the bargain by serving as messenger between the fairy court and the powerful wizard Baba Yaga. The only thing that could break the fairy's spell is if Tobi somehow manages to win the hand of a prince. Given Baba Yaga's home is located in a monster-infested thicket, that seems unlikely.
But then a young woman named Robin Weatherwax comes to Russia to study magic under Baba Yaga. Before she's even started her first lesson she's gone and rescued a prince: a prince who loves cats, as it turns out. No matter what, Tobi can't risk accepting the prince's friendship. He'll slash those spell-breaking prince hands to ribbons if he has to. If he doesn't, he could very well lose his hard-earned cathood.
