Zipp is Pipp and Pipp is Zipp, and up is down and left is right, and oh my hoofness! Okay, well, it's not that dramatic, but the Zippsqueaks are totally worried because Zipp hasn't posted in three hours. And Pipp can't focus on the Royal Dinner because she had to track down the pony responsible for the freaky switch. Luckily, Sunny, Hitch, and Izzy are in Zephyr Heights to help. Everypony, grab your popcorn. This is going to be a good one!
