Paifu, a half-vampire half-werekoala, is always getting into trouble with his best buddy, José the ghost. But when the Monster Flu sweeps through town, the fun and games are over. If the monsters don't get the medicine soon, everyone will die! With all the adults sick, it's up to the kids to save the day!
