Continuity mistake: In the last classroom scene, the blue oval design on Gabby's cap appears and disappears between a few of the last shots of the scene, first when Vinnie runs up to Professor Q (because Rocket went ahead and switched both his and Gabby's test papers) and later when Professor Q was talking about how he was ∞ proud of Vinnie.
Continuity mistake: After Vinnie completes his lifetime of tests, Rocket proceeds to mark them and tells him that he failed some tests but that he passed his Art "with a lovely rendition of the Mona Lisa." When Rocket is seen holding up the paper and when the camera shows Vinnie sitting at the desk explaining what he actually drew, the tick on the paper is different between the 2 shots.
Continuity mistake: When Rocket pulls out his printing calculator to calculate the amount of lifespan Vinnie would have left, he lets Vinnie make a decision but he speeds up his decision-making by reading off the countdown timer that magically appeared on his calculator. The calculator is also different in the close-up with the missing thermal printer and a different keypad layout, as well as a different number, where the number is transcribed as what Rocket says is "30484800 minutes 57 seconds" and when the calculator display is shown in the close-up 8 seconds later, it shows the number "20484 80056."
Continuity mistake: After Vinnie talks about his "responsibility to have fun", he swallows his Squid Shake, while Rocket didn't swallow his (his cup can be seen in the shot). When baby Professor Q cries, both Vinnie and Rocket throw up, even though Rocket didn't swallow his drink.
Continuity mistake: At the start of the episode when Vinnie and Rocket search for Gabby's pet badger, after updating her, Vinnie goes back into his bedroom where Rocket is seen in the room pulling out a pirate's peg leg, Professor Q's "oscilloradioscope", and a baking soda volcano from behind his back. However, for about a frame, the other 2 items were also peg legs before turning into the respective item. His mouth also tilts between frames.
