The monstrous Turbo Toilet 2000 is determined to take revenge on George, Harold, and Captain Underpants.

George and Harold have created a new breed of justice. With the head of a dog and the body of a human, this heroic hound digs into deception, claws after crooks, rolls over robbers, and scampers after squirrels. Will he be able to resist the call of the wild to answer the call of duty?

All the other dogs make fun of Oscar the dachshund until one Halloween when, dressed as a hot dog, Oscar bravely rescues the others.

With a cute kitten and a remarkable robot by his side, our heroes must save the day by joining forces with an unlikely ally: Petey, the World's Most Evil Cat. But can the villainous Petey avoid vengeance and venture into virtue?

Is Dog Man bad to the bone? The canine cop is sent to the pound for a crime he didn't commit! While his pals work to prove his innocence, Dog Man struggles to find his place among dogs and people. Being a part of both worlds, will he ever fully fit in with one?

Dog Man hasn't always been a paws-itive addition to the police force. While he can muzzle miscreants, he tends to leave a slick of slobber in his wake! This time, Petey the Cat's dragged in a tiny bit of trouble -- a double in the form of a kitten clone. Dog Man will have...

George and Harold, and their doubles, Yesterday George and Yesterday Harold, have a good thing going. Two of them go to school, while the other two hide in the tree house and play video games all day-then they switch! But when their malicious gym teacher, Mr Meaner, creates a method of mind control that turns their fellow students into attentive, obedient, perfect children, the future of all humanity will be in their hands!

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.

Having changed the course of human history after unwittingly wondering what could be worse than going to prison, George and Harold are catapulted through time back to their kindergarten days, where they are subjected to a sixth-grade bully and a cluelessschool principal.
