Plot
On the Jolly Roger, Sharky and Bones spot Bucky. Captain Hook makes sure Jake and his crew won't bother him with his newest invention: the Foggy-Fogger 500. Captain Hook activates the machine so that it creates fog around the Jolly Roger. Meanwhile, Izzy finds her beach ball when Skully spots land ahead. This surprises Cubby, who knows there's no land on his map. Cubby knows it as Mysterious Island, which appears out of nowhere, then disappears just as quickly, and no one knows why. Jake and his crew decide to solve the mystery.
Captain Hook spots Bucky heading to Mysterious Island, and Sharky knows the island's legend, as well. Captain Hook orders Sharky and Bones to set sail for the island before making fog to hinder Jake's crew's progress. Luckily, Bucky fans the fog away. Izzy then finds Mysterious Island gone, followed by Captain Hook's crew. As Jake informs Captain Hook and Mr. Smee about Mysterious Island, it appears and lifts up both ships. Sharky and Bones sing about why Mysterious Island disappears and appears again.
Jake and his crew head to the island and notice many strange things. As Captain Hook's crew prepare to head to the island to solve the mystery, Jake warns his crew about the ground being very slippery. Cubby slides away, so Jake and Izzy save him with a seaweed rope. Captain Hook and Mr. Smee then slide into seaweed before they, Sharky, and Bones are confronted by Jake and his crew. As Captain Hook claims the island for himself, he orders Jake and his crew to get off.
Just then, the island growls, revealing it to be a giant sea turtle. That is why it appears and disappears in the Never Sea. As the sea turtle starts to sink, Captain Hook's crew slide away. Izzy uses her pixie dust for Jake and his crew to make it back to Bucky while also bringing Captain Hook's crew back to the Jolly Roger. The sea turtle then swims away.
Back on Pirate Island, Jake and his crew put all the gold doubloons they collected into their Team Treasure Chest. Jake wonders where Izzy, Cubby, and Skully are, and they appear from behind the palm trees. Meanwhile on the Jolly Roger, Mr. Smee sees a tiny island up ahead. Captain Hook is about to claim it for himself when he discovers it to be Tick-Tock Croc, who chases Captain Hook across the Never Sea while Mr. Smee watches on.
