Irrepressible friends George and Harold create a new comic book superhero, Super Diaper Baby.

Whenever Dragon wakes up groggy, he always does everything wrong, like sweeping a hole in his dirt floor, or reading an egg and frying his newspaper.

Dragon is lonely so he goes looking for a friend and when an apple falls on his head he is convinced that he has found one; but at home Apple is quiet and unresponsive, and when a visit to the doctor only makes things worse, Dragon mourns the loss of his friend--until an apple tree grows where Apple is buried.

Big Dog and Little Dog like going for walks, though having a bath afterwards is not so much fun.

When George and Harold hypnotize their principal into thinking that he is the superhero Captain Underpants, he leads them to the lair of the nefarious Dr. Diaper, where they must defeat his evil robot henchmen.

Dragon has a busy and fun-filled Halloween, turning six small pumpkins into one big jack-o-lantern, going to a costume party, and taking a spooky walk in the woods.

Big Dog and Little Dog get in trouble when they play in the house.
