The toons take Marvin the Martian's class, and head to space. Buster tries to cheer up a homesick Babs, Plucky searches for a space outfit, and Sweetie is too obsessed with a video game to notice any of it - even when the aliens attack!

Plucky goes home with Babs and Buster for Spring Break and quickly becomes the new star of Burrowville, while Hamton and Sweetie embark on the adventure after accidentally missing their train stop.

In this two-part episode, Sweetie and Buster's plan to give their friends a non-scary Halloween goes awry.
