While at Ooey Gooey World, Tommy spots the volcano where the princess lives. "Look, there's the castle! Let's go see the princess, Chuckie." Tommy said. But Chuckie implied to his best friend that they should stay inside the ride they are on. "Come on! I'll show you a shortcup." Kimi shouts, as the other babies get off the ride, in which Chuckie thinks this is a bad idea. "What are waiting for?" Kimi asks. "Just be brave, Chuckie. Right behind you, Kimi." Chuckie replies as the babies escape Ooey Gooey World, and this makes Kira find out. "Kimi! Madame, the babies are gone!" Coco LaBouche, upon hearing Kira's alert, also finds out herself and has Kira get the babies back before Chaz also finds out. Kira then has Coco's security ninjas search around Euro Reptar Land to find the babies.
Meanwhile, while "Life is a Party" by the late Aaron Carter plays in the background, the babies are on a mission to go to the castle on the volcano. Chuckie also tags along, but is learning to be careful while still having fun with his friends. After overcoming several obstacles in their way, they reach their destination and find the princess, only for her to go back into the castle. Encouraged by his friends, Chuckie tries to open the door, but then finds out that it's a dragon surrounding the door's ring. The ninjas also arrive at the castle and pick up the babies, while one picks up both Phil and Lil without hesitation. The ninjas and the babies then make their way back to Chaz and Coco. "At least we didn't have to walk all the way back here." Phil said. "Because if we did, our feet would be hurt by now." Kimi replied.
