Party Pooped has an unusual cause of regional censorship. Specifically, I've heard that this is the only episode of the show Treehouse TV never aired, mainly due to its title being too gross for the younger audiences watching it. Nevertheless, I decided to continue on with my viewing regardless of this issue, knowing that opinions are stronger than censorship.
At the Castle of Friendship, Twilight is nervous about the arrival of Yakyakistanions. She hopes to make a good first impression, knowing that Celestia is counting on her. When the yaks arrive, she offers them a table of traditional Yakyakistan cuisine, but to her surprise, the yaks hate the food, and begin to destroy the palace. As she and her friends clean up, Twilight asks Pinkie Pie to help make the yaks feel at home before the welcome party begins that evening.
Pinkie's first stop is Sweet Apple Acres, where she helps Applejack make hay beds for the yaks. But after a few minutes, the yaks destroy the mattresses. On a picnic with Fluttershy, she has her animal friends wear fake antlers, but after one of the ducklings trips over a pebble, the yaks chase after the animals. At Carousel Boutique, Rarity tries giving the yaks some fabric from the Crystal Empire, but they wreck her display. Even Rainbow Dash destroys a cloud to create some snow, but the yaks aren't impressed.
Back at the castle, the group hold a meeting to discuss how poorly things have been going for their guests. Pinkie decides to take the party planning into her own hands. After arriving at Sugarcube Corner, she chats with Gummy, eventually getting an idea. Twilight and co. check on her, when Gummy spits out a note saying she'll be back in time for the party. However, the desserts Mrs. Cake made for the yaks aren't received well, causing Twilight to get even more nervous.
Meanwhile, Pinkie embarks on a journey to Yakyakistan, but the train stops at a junction because of some sheep crossing. There, she runs into Cherry Jubilee, who's making a delivery to the Crystal Empire, offering to give her a ride. Midway through the trip, Cherry falls asleep, causing their cart to fall into a pit. Back in Ponyville, Spike attempts to appease the yaks by playing piano. But after he steps away from the keys, they discover it is playing by itself. This causes them to become so furious, they not only leave Ponyville, but declare war on Equestria due to how poorly they were treated.
After a long journey, Pinkie eventually makes it to Equestria's northern border, with the guidance of Cadence. As she continues her travels, Twilight and co. find a trapdoor within Sugarcube Corner. Back in the northern border, Pinkie encounters a yeti-baboon hybrid, but quickly hitches a ride on a sled with a young yak. But just before she can enter the gates, the sled slides back all the way to Ponyville, effectively making Pinkie's journey a wasted effort.
Back at Sugarcube Corner, Twilight and co. are exploring the secret party cave. They find files for lots of different ponies, cataloging their interests, as well as loads of party supplies. Pinkie hears her friends talking and slides down, thinking her journey has made her a failure. However, her friends assure her feelings, and she recalls the ponies who helped her along the way, allowing her to get another idea. Luckily, the yaks can't leave Ponyville because of sheep crossing, giving Pinkie time to help overhaul the party plans.
During the celebration, Pinkie apologizes to the yaks, saying that instead of trying to make Equestria feel like their home, she and her friends should have shown off what made Equestria special so they can understand why the ponies enjoy living there. The yaks are moved by Pinkie's apology, calling off their declaration of war. This allows the ponies and yaks to become friends, and Pinkie seals the deal with a very strong hug.
I thought Party Pooped was a pretty good episode. While I didn't like that Twilight was making some stupid decisions in handling the yaks' welcome to Ponyville, I thought Pinkie's journey allowed her to realize how far she's come since the beginning of the show. There were certainly some fun scenes, including the sleigh ride, and Pinkie's brief musical career being a Beatles reference. I'm proud that I'm one of the few Canadians who saw this episode outside of clips or pictures, and feel that Treehouse TV should have gave this story a proper chance, even if its title sounded gross.
