Moon Circus is the first half of the twenty-first episode of the second season of Ready Jet Go!.


Carrot is about to turn 250 Bortronian years old, and the kids have set up a backyard circus to help him celebrate. They all notice that Earth's gravity makes it hard to perform their circus stunts, so they take the whole circus to the Moon, where its 1/6th gravity makes all their stunts much easier!


Today is Carrot's 250th birthday, and the kids are planning a surprise circus party for him. The kids know Jet's history of not keeping secrets well, so they advise him not to tell Carrot about the surprise. Carrot decides to go outside, worrying the kids, but Jet has an idea. Jet takes a big wooden slab and paints the sky on it, as well as the kids, fooling Carrot into thinking that the painting is really the kids, and hiding the circus stuff in the process. After Carrot goes back inside, the kids are relieved. Jet notes his character development of learning to keep a secret better but loudly says that the gang is planning a surprise party for him, and Carrot overhears. Carrot decides to tell them that he knows so he can help them. Celery advises Carrot to not let the kids know that he knows. Carrot says he'll try since it's not every day that he turns 250 Bortronian years old, and Celery says that he's still a spring chicken in her eyes. Carrot says that he was trouble keeping secrets, and Celery says that it's a shared trait between him and Jet. Jet overhears and asks if it's about them both loving prune juice with lemons squeezed in it, and his parents say yes to hide the secret. Meanwhile, the kids are having trouble doing their circus tricks, since they can't jump as high as they'd like. Jet laments that they can't jump as high as they could on Bortron 7. Sean says it's because of Earth's gravity. Jet thinks this calls for a song, and we get a reprise of "What Goes Up (Must Come Down)". TBC
