Shake Your Booga/Cosmic Comicon.Shake Your Booga: While Betty and X-5 are waiting for Sparky to finish using the bathroom after ingesting too many montegoberries, Sparky finds a set of bongo drums at a yard sale, which he buys as a birthday gift for Regeena. As Sparky plays the drums, it awakens Shaka Booga, who discovers that her drums missing. Finding Atomic Roger nearby, she manages to have him take him to Earth and Regeena's party. This does not go unnoticed by Admiral DeGill, who takes a furious Betty (about to dance with Chaz) and Sparky to discover why Atomic Roger has been taken hostage and why she is heading for Earth; Shaka Booga arrives at the party in her absence, and turns all the partygoers into cave-kids (Duncan, however, is surprisingly unaffected), ordering them to steal shiny objects using the power of the bongos. Later, Admiral DeGill orders Betty back to the party; Betty is overjoyed at the news (believing the case was being reassigned), but to her horror discovers the truth after returning to the party. Betty and X-5 manage to fight off her cave-kid friends, capture the bongos, and get Shaka Booga to return her friends back to normal, in exchange for the bongos. (Villain: Shaka Booga)
Cosmic Comicon: Noah invites Betty to a comic book convention, where he shows her a new comic book he authored, titled Atomic Chick, loosely based on Betty's adventures. While Betty chastises Noah for not keeping her secret, Noah reassures her that a "small indie comic" wouldn't garner much attention — only to find that Atomic Chick is a hit, and everyone is dressed as characters from the comic book. Still, Noah reassures Betty that all names have been "slightly modified to protect the innocent" in order to preserve Betty's secret: Sparky is "Spark Dude", X-5 is "Q-7", and Admiral DeGill is "Commander LeFin" (all three are at the convention, dressed as their Atomic Chick counterparts). Even Regeena is dressed as "Dr. Brainy", the Atomic Chick counterpart to Dr. Cerebral. Meanwhile, the angry Dr. Cerebral is offended by "Dr. Brainy", and goes after Regeena to steal Brainy's version of a part needed for his doomsday device (unaware that Cerebral himself has the working version and Regeena has the lookalike). Cerebral and Regeena manage to switch their parts, while Betty takes the opportunity to leave with X-5 (who dislikes Noah's portrayal of him being Q-7) to lead a preemptive strike on Cerebral while Cerebral has Regeena's knockoff. However, Cerebral quickly realizes this, and returns to Earth to steal his original back from Regeena. Betty takes the opportunity to take her role as Atomic Chick and disarm Dr. Cerebral; Cerebral is later beaten up by the legions of convention-goers. As for Noah, he intends to make a second issue of Atomic Chick, but abandons the idea after a horde of fans mob him for "original sketches". (Villain: Dr. Cerebral)
