- Defictionalization: Attempts have already been made to craft the MMMM in real life, such as this one and this one. It's absolutely plausible that a real life pastry chef would combine those ingredients somehow.note
- What Could Have Been: According to a blog by writer Amy Keating Rogers, a scene was planned in which Twilight commends Applejack for her self-control, at which point the guilt-ridden AJ admits that she was the fourth one to take a bite—she simply covered her tracks so well that no one suspected her—thus giving all six ponies involvement in the plot. This was cut due to time constraints. Seemingly hinted at in the final product, as Applejack can be seen looking slightly guilty when Pinkie starts investigating who ate all the other desserts.
