The scene in which Pepper and Captain Cuddles eat spaghetti is a reference to Lady and the Tramp. There is another reference to the scene in the My Little Pony episode "The Perfect Pear."
The book Blythe is reading is a parody of Twilight.
Pepper has a crush on another animal and tries to change herself to impress him. In the My Little Pony: Friendship is Magic episode "Simple Ways" Rarity does the same thing. Both Pepper and Rarity are voiced by Tabitha St. Germain and both episodes aired on the exact same day.
