Based on an idea from ILoveLadies2.

"These are AU versions of Applejack and Rarity who are Filmation Ghostbusters (no relation to the 1984 movie of the animated spin-off The Real Ghost Busters). They are going through the transformation sequence from the cartoon to get into their uniforms. The guys used a device called the Skelevator to take them to another dimension where a giant hand threw them onto a web that stripped them to their underwear then they were placed on a conveyer belt made of bones that took them into a machine that dressed them. Applejack enjoys the ride, while Rarity hates being stripped in such an open area."
