Before the events of Mighty Pups, comic book and superhero fanatic Rubble made a fantastic discovery. While he was alone in an abandoned cave, he discovers a secret laboratory. Scared and panicked, Rubble runs around trying to find an exit but realizes he's accidentally pushed a button. A giant spider emerges from a glass box, and Rubble is surprised that this spider has a face, human eyes and a smile. "I am Spidey!" says the spider, happy to make a new friend. "Some guy experimented on you and all these years, you were locked here?" "I am Spidey!" confirms the spider. "If only I could be Spider-Pup.." "I am Spidey?" "No, nothing." The puppy then hides this strange spider in his puphouse but he quickly realizes that it has magical powers. A new villain tries to capture Spidey but Rubble is ready to give up everything to help his friend the spider.
