By Virtuoso of Insanity:
While taking a bath, Maximus is enraged with Minimus, and when he rears up to strike the little creature, Minimus comments that his voice is beautiful, and asking if he had ever considered a singing career. Maximus decides to take his show on the road, playing at the fanciest theatre in the Galaxy. There's only one thing wrong: His performance speakers are hypnotizing the audience in order to meet his expected standards! Meanwhile, Betty and her band have a gig for a social event (covered by the school paper), but Betty is called away on her mission, leaving the band behind and making them feel as if she has forgotten them.

Switch-mo-tized:
While volunteering at a magic show, a robot magician named Switchmo switches Sparky and Minimus's bodies--now Sparky is stuck in Minimus's body, and Minimus in Sparky's! After a failed attempt to stop Switchmo, Betty and Maximus are forced to team up in order to stop this mad magician from declaring himself the Supreme Overlord of the Galaxy. Meanwhile on Earth, Penelope wants Betty's locker, so she tries to sabotage it in order to make Principal Peterson think that she isn't maintaining school property well.
