Good cold open. Pinkie Pie was very pinkie at the start. I also got significant Willy Wonka vibes here. But it looks just as boring as a normal factory. Pinkie is still being as typically Pinkie throughout the episode. Sans was a good character throughout the entire episode. The visual gags were great as well. The return of Weird Al in a more subdued role was a great choice for this episode, with a call back to his time before the factory. The montage with pinkie doing gags and the "science" of comedy was fantastic as well. The song (which isn't a surprise with the musical genius that is Weird Al at his best) was absolutely fantastic, showing just how much of a range he really has. Overall, this was a fantastic episode and a great way to start off the second half of the final season.

My grade: A-
