Plot
The story begins as the peaceful pets of Petootie Valley are attacked by monsters, led by Scorpan, who kidnaps four puppies and takes them away to Midnight Castle. Enraged, Aspen, a Petooties Husky, takes to the skies to try to find someone who can help them defeat Tirac, a centaur-like demon whose plan is to use these pets to pull his Chariot of Darkness. On her way, he crashes into 12-year-old Megan's well and asks her for her help. Megan is at first reluctant to go but after being confronted by the monsters, she sets out with the pets to rescue them.
At Midnight Castle, Tirac has the smallest puppy, Gem, taken to the dungeons, and uses the Rainbow of Darkness to turn the other three puppies Scorpan captured into dragons. He tells Scorpan to bring him a fourth puppy by midnight, threatening to behead his friend, Roscoe, the baby Dachshund.
Megan, Firefly, and the puppies Jazzy, Scout, and Mocha go to see the Moochick, who has magic powers and might know how to defeat Tirac. On the way, Mocha falls off a bridge into the river and Megan jumps after her, from which they are rescued by the Sea Pets, who tell them to call on them if they need help again. Megan and the puppies find the Moochick, who says that to defeat Tirac they must take away his Rainbow of Darkness, which gives him his power. He also gives them the Rainbow of Light, which can help defeat Tirac.
Arriving at Midnight Castle, Megan and the puppies cross the moat of raging water with help from the Sea Pets. Meanwhile, Scorpan fails to get a fourth puppy for Tirac, who threatens Roscoe again. Scorpan releases Roscoe and Gem from the dungeons. Jazzy is captured by Tirac, who turns her into a dragon. Scorpan enters, attacks Tirac's guards, and runs outside with Megan and the puppies. With four corrupted puppies, Tirac rides his Chariot of Darkness. Tirac defeats Scorpan, nearly killing him, while Megan rides Aspen and knocks the Rainbow of Darkness out of Tirac's hand. The puppies fight Tirac's guards over the Rainbow of Darkness, but in the end, Tirac gets it back. Megan unleashes the Rainbow of Light, which is actually very small and does nothing at first. Tirac uses the Rainbow of Darkness on the Rainbow of Light, which fights back, overpowers the Rainbow of Darkness, and destroys Tirac. Everything Tirac transformed with the Rainbow of Darkness is restored to its original state, including the puppies and Scorpan, whose original form is a human prince. Roscoe, however, has always been a dog like the other pets.
