There's a monster living in the woods outside of Doug's town and Doug and his friends happen to make its acquaintance. Their first reaction is fear, until they find out they kind of like the little monster. That's when they find themselves being pursued by the bad guys who want the monster for themselves.
Doug also has other problems to contend with -- namely, will he or snobby 8th-grader Guy Graham be the one to take Patti Mayonnaise to the Valentine's Day dance? And you thought your life was complicated.
Screenplay: Ken Scarborough
