A troll goes in Jake's home: the troll wants to stay there beacause he hates the sun. Jake has to hide him! Fu gets prime tickets to a baseball game and desparately wants to go, but Lou Shei (Grandpa) can't take him because he has to train Jake. So after a few warnings, Fu 'walks' himself. Unfortunately, a dogcatcher takes this opportunity to catch Fu in order to be used to cure her dog allergies (and it's not in a manner in which the dog survives).
