Sanzo Hoshi goes to the Space Pirates and tells them to release the D-Teams' parents. They instead force him to move the giant boulder blocking the entrance to the cave where the Cosmos Stone is hidden.
Meanwhile, the Alpha Gang picks fruit for a peasant farmer who, in return, gave them directions to Lotus Land, the place where the Fruit of Eternal Youth grows. While searching, they find the mountain where the D-Team are, and Ed has Tank dig a tunnel up to the top of the mountain. As Sanzo chants to move the rock, Tank's digging causes the rock to fall over, opening the tunnel. The Space Pirates quickly head inside, followed by the D-Team.
Gavro summons Carcharodontosaurus to fight Tank while Sheer summons Lanzhousaurus to attack the D-Team, who counter with Ace and Chomp. After activating their Element Boosters, the D-Team and Alpha Gang beat the Space Pirates, but Foolscap beats Zoe to the Purple Cosmos Stone.
The episode ends with the D-Team and Alpha Gang realizing they have lost contact with the Backlander.
Gavro/Sheer vs. Max/Rex/EdEdit
Gavro summons Carcharodontosaurus to fight Tank, but it doesn't go so well for Carcharodontosaurus at first. He tries to bite her, but Tank dodges it and rams him into a wall, biting him in its stomach. Sheer then summons Lanzhousaurus to attack the D-Team, and Max summons Chomp . Lanzhousaurus drains much of Chomp's energy with Power Drain , and Ace is summoned. Tank continues to knock Carcharodontosaurus away, which is the reason for Sheer and Gavro give their dinosaurs their Spectral Armor forms. Max and Rex give Chomp and Ace their DintoTector forms, but not for Tank. As the Alpha Gang arrives, they see that Carcharodontosaurus is beating up on Tank. Ed activates her DinoTector form.
Ace grabs Lanzhousaurus's tail and smashes it into a wall with Cyclone. Chomp uses Ultimate Thunder to defeat Lanzhousaurus, destroying its Spectral Armor. Tank uses Ultimate Earth to defeat Carcharodontosaurus, destroying its armor.
Max, Rex, and Ed win
