While enjoying a harmless game of softball, said softball ends up landing in a neighbor's yard. This normally wouldn't be a problem, but, this neighbor's yard is inhabited by a dog named Carnivorous. To make matters worse, the softball belongs to Mark and Derek. If Angela can't get the ball back, she might not make it to her next birthday. She and her friends try to come up with a plan. Gordy is used as a decoy and the kids manage to retrieve the ball. They also free the dog from his yard in the process. Carnivorous lives up to his name as he chases everyone up trees and on top of cars. The only way the kids can get rid of the dog is to throw the ball back into the yard! Angela is back at where she started. She has no choice but to take matters into her own hands and go into the dog's yard herself. She marches right into the yard, only to be immediately chased into a garbage can! Mark and Derek turn out to be the heroes of this tale when they come home and reveal that Carnivorous is really Fifi and quite nice once you get to know her. (thetvdb.com)
