Super Cash Girl! And The Ugandan Knuckles!

The episode begins with Parker Waddleton and his sister Imogen Iceburg leaving a movie theater and seeing what appears to be a comet. Chillsa Froster and Hootie Hurdleson, who staff an early-warning radar station at the Otterson Science Lab, alert Super Cash Girl of an approaching alien. Super Cash Girl begins to search for the alien but gives up after finding nothing. Meanwhile, Vigor Springley and Petey Plumford are having a birthday party at Vigor’s house, where Vigor accidentally breaks her dad’s prized "Striped Cheetah" bowling plate. Upon landing, the comet turns out to be a famous weird Red echidna meme named "Ugandan Knuckles" (Knuck, for short), which emerges and convinces Vigor to lie to her dad claiming, "A little fib couldn't hurt anybody." Vigor lies to her dad and claims that Petey broke the plate by using a gadget. Vigor’s Dad believes her, but Vigor soon discovers that her "little Knuck" grows larger every time she lies. Despite this, she tells Parker that Lucy fed the plate to a echidna, which she believes.

Later that night, Peter, Parker, and Lucy form an angry mob and confront Vigor about her lies. When she tells a lie about alien hedgehogs coming to Earth and destroying the plate, which Parker likens to a movie he saw, Knuckles grows to be a monster who holds Vigor prisoner and starts wreaking havoc in the city.

Super Cash Girl is summoned and forced to pursue the Knuck and Vigor in her Bisket-Mobile as it tries to escape by climbing to the top of the water tower. Super Cash Girl transforms the Bisket-Mobile into the Bisket-Plane and flies into the sky but ejects after finding out the Bisket-Plane is unarmed, causing her to be caught by the Knuck. She is grabbed and squeezed until one of her plungers pops out and is about to be eaten when her butler, Ethan Sydney, informs her that Vigor is the only one who can stop the Knuck. Vigor then admits the truth about her lies to her parents (who are watching from below) and as she tells the truth, the Knuck shrinks into nothing but air. As Vigor apologizes to her parents and everyone else, Super Cash Girl stares at her signature spotlight as another Knuck lands in Otterson, only this time it is in a blue color.
