Paifu, a half-vampire half-werekoala, is always getting into trouble. With his trusty sidekick, Jose the ghost, he's out stealing watermelons, befriending murderers and causing a ruckus. But not everything is fun and games when the contagious Monster Flu sweeps through town. If the sick monsters don't get some medicine within a month, everyone will die!
But the only one who has the medicine is a witch who lives high atop Horned-Own Mountain... 750 miles away! With the help of a former sumo wrestler, Paifu, Jose, and tagalong Arpon are off on an adventure! But will they get the antidote in time or will they become victims themselves?
