Enter the Cat - S2.E29

Jackie finds a highly valued cat statue. Anyone who is scratched by it is magically transformed.

Forced to steal it back for a gangster when Jackie is tossed into a jail cell, Jade is able to retrieve the statue, but gets scratched by it in the process.

Uncle had been researching into the Cat’s legend, and says that the cure lies within. Jackie soon has an epiphany, and decides the Cat is too dangerous to be in a museum. So he smashes the statue, thus releasing a purple-colored gas that cures Valmont and Jade. With that, Jackie then realizes that “The antidote lies within” meant that the antidote was inside the statue itself (and not within a person, despite what he thought at first).
