Kinga is ecstatic with the currrent progress of the Bubbulat-R, as she continues to expand the Mystery Science Theater 3000 brand into a new medium. With Tom currently hogging the spotlight in Johnny Jason, Teen Reporter, she decides that Jonah and Crow need to see some action. She has Ardy flush them an issue of the 1940s costumed crimefighter Black Cat.
Black Cat and Jonah
Jonah and Crow find themselves having appeared in the sidecar of Black Cat's motorcycle. As they marvel at being back in the 1940s, another Moon 13 Ad Trap for Totino's Pizza Rolls is prematurely set off. In the chaos, Crow goes missing.
Meanwhile, the nefarious chess-themed crime boss Rook is seething over how Black Cat has been taking out criminal operations left and right for the past year. So he proposes creating an underworld chamber of commerce for the express purpose of eliminating such crimefighters. His first scheme involves a contest with a $50,000 prize for the person who can ferret out the secret identity of Black Cat
Kinga is confounded when Growler makes an unexpected appearance in the Black Cat comic. An examination by Synthia reveals that the bubble columns for the two comic books in the system are starting to merge. Max points out that comic book nerds love this sort of crossover action, so they leave it be.
Black Cat and Jonah, Continued
Rook continues to ramp up the publicity for his Who Is Black Cat contest and hires Jonah in his role as a DJ to promote it on the air. Hollywood starlet Linda Turner is not thrilled with this turn of events and goes out to investigate the situation as Black Cat. She stakes out the post office where the contest entries are being sent and tails the trucks that pick them up, noticing that Jonah is doing the same thing. Going up a narrow mountain road, a couple of goons in the rearmost truck open fire on their pursuers. Jonah loses control of his car and goes down the mountainside. Black Cat follows and pulls him out of the flaming wreckage. Seeing that he's now okay, she resumes her pursuit of the trucks, which lead her to an isolated castle. Suddenly, a bascule bridge she's crossing opens and she is unable to stop in time before being sent flying into the river. Before we can learn Black Cat's fate, the scene abruptly shifts to a creepy house with an overgrown lawn, where the previously AWOL Crow shows up.
This unexpected development has Kinga seriously annoyed. An examination by Ardy reveals that there was still some residue left over from their test run with Issue #2 of Horrific and it's seeped into the tanks. Kinga decides to let it continue.
Tail of Death
Joe Hatter obsessively attempts to create a tissue expansion drug, but fails time and again. His brother Amos recognizes how unhealthy Joe's obsession is, but is unwilling to have him institutionalized. One night, Joe has an epiphany about what he needs to do and immediately heads down to his lab. He injects the new formula in a rat, but instead of growing, it shrinks instead. The rat bites him, which gets the formula in his own bloodstream, causing him to shrink as well. Amos hears the commotion and discovers his brother in his diminished state. Amos uses this opportunity to lock up Joe in an old parrot cage. But the inhumanity of his actions cause Amos to feel guilt and he attempts to develop an antidote. It works, but before Amos can explain some of the side effects, an enraged Joe strangles him. Since their house is so out of the way, Joe figures knowledge of his murder of Amos won't get out and he buries the corpse in the basement. Going over Amos's notes, Joe learns that the antidote's effects may be only temporary. The antidote's duration ends before Joe can whip up another batch and he is killed by a stray cat.
