"Moon Circus": It is Carrot's 250th birthday. The kids make a circus to celebrate. They tell Jet not to tell Carrot, but Carrot ends up finding out anyway. The kids can't do their stunts on Earth because of the high gravity, and Carrot strains his back while trying to do a famous flip of this. In the end, the decision is made to transfer the circus to the moon, where everyone can do their circus tricks due to the low gravity . "Every Day is Earth Day": Today is Earth Day. The kids are making posters to celebrate. The kids travel around the Earth to find out what makes Earth so special. Then they use a Bortronian hot air balloon to get to the local DSA Earth Day celebration. Mitchell performs a poem about Earth. Carrot mixes up "toaster" and "poster" and presents a toaster, much to Mr. Peterson's annoyance . The kids arrive in their hot air balloon, and Jet leads everyone in a big song about Earth.
