The pups are all dressed in their own superhero outfits for the Apollo the Super-Pup marathon, but after 12 episodes, the pups are falling asleep. As Rubble soon joins the others, he enters another dream sequence, where he wakes up in time to watch as Apollo is caught by surprise by his arch-enemy, the Spider King, and captured. At that point, to Rubble's shock, Apollo calls him for help. Though spooked, Rubble goes to tell Ryder. Ryder laughs a bit, which made Rubble felt like Ryder doesn't believe him, but Ryder says he does. As it turns out, Ryder knows where the Spider King's lair is, and summons the pups.
Once topside, after Marshall trips over their bowls full of popcorn, they get their orders: Rocky will help free the bunnies and Apollo, Skye will fly them to safety, and when Rubble argues that Apollo talked to him, Ryder assigns him to seal up the Spider King's cave once everyone is rescued. With that, the team deploys and heads off to save Apollo.
They soon reach the Spider King's cave, and arrive just as the Spider King recedes into his inner lair. After avoiding the tar pit in the middle of the room, they find Apollo, but due to how high up he is, Ryder summons Marshall and Chase for additional support.
Rocky gets to work freeing the bunnies, as Chase and Marshall arrive, though Ryder has them cut their sirens to avoid alerting the Spider King. With Marshall there, Rocky frees Apollo, who soon senses the Spider King coming back, so he and Rubble quickly seal the door to the Spider King's inner lair, only for it to be temporary as the Spider King starts to bash his way out. However, it buys them enough time to free all the bunnies and for Skye to take them to safety.
Soon enough, the Spider King bashes his way out, only to be confronted by Apollo, Ryder, Rocky, Rubble, Chase, and Marshall, who attempt to overpower him with web balls, tennis balls, water cannons, and Apollo's own skills. However, seeing that won't work, Rubble and Apollo clear the way so Ryder is able to lure the Spider King into getting stuck in the tar pit. With the Spider King stuck, everyone else is able to escape and Apollo and Rubble seal the cave so the Spider King can't get out again.
With the Spider King subdued and sealed away, Apollo thanks the PAW Patrol for all their help, and Ryder assures him that if he ever needs help again, he can call on them for it. With that, Apollo departs to return home, and as Rubble watches him leave, Rocky tries to shake him out of his dreamy state, which brings Rubble back to reality.
As Rubble wakes up, Ryder has joined the pups, who have all waken up themselves, and the others reveal that Rubble slept through the rest of the marathon, much to his disappointment when he tries to explain his dream to them, but gives up knowing they won't believe him. The episode ends as the team recite the last part of Apollo's show narrator with this saying:
Narrator: "Tune in next time for when Apollo saves the day..." PAW Patrol: "His own super way!" (laughter)
