Finally we found out more about the yaks! For about two years now, I wished to see more of their culture and how they live and especially the inside of the gates of Yakyakistan. "Party Pooped" in Season 5 left me craving for more as Pinkie slid back to Ponyville right before she could enter Yakyakistan, but now, I finally got a look inside of their kingdom!
And I was surprised to see that the yaks live in such simplicity. Where I expected to see stone houses, especially after the official comics revealed that Yakyakistan has a castle last year in March, they live in tiny clay huts! And their festival, whose name I sadly couldn't speak nor type to save my life, is just consisting of a ceremony where the yaks publically destroy things together.
As "Party Pooped" already hinted at, the yaks are apparently a very belligerent folk, a proud war nation that prides themselves on their physical and military strength, as one of their most sacred traditions is such a violent one.
It does make me eager to see the yaks in an actual war one day, though, I hope this won't be a war that is fought against ponies.
A particular detail I caught in this episode makes clear that such a war might be very devastating and come with great losses for Equestria:
In a few shots, we see that the yaks grow corn and crop. The fact that they are able to do this, despite the harsh, arctic environment of Yakyakistan, is providing evidence that they have to possess some means of magic as well. While this does not confirm something I wondered about after "Party Pooped" aired, if the yaks have weapons that can negate magic to balance out their disadvantages against unicorns and the alicorns in a war, it gives a hint that Equestria's magical adepts maybe wouldn't even have the advantage of magic over the yaks if it would come to a war.
And since the yaks' bodies are evidently not able to produce any magic, they most likely rely on powerful magical artifacts or machinery that allow them to grow their food despite the cold weather and that maybe could be used as weapons as well.
We've also seen that the yaks have lost nothing of their rather aggressive nature and of their attitude of easily getting angry, even though Prince Rutherford restrained himself from declaring war on Equestria this time, so the prospect of conflicts between Yakyakistan and Equestria is still a scary one.
Letting aside what I just said, there is also one interesting sentence by Prince Rutherford that further points at it that the yaks are a force to be reckoned with:
"And that how yaks defeat evil and save world!"
Granted, he spoke this sentence while sitting at the fire with Pinkie and the other yaks, the fire that is used by them as a place to tell stories. But "Story" does not equal "Fiction" and this term is often used to talk about real events as well. It would also beg the question why the yaks should tell each other a fictional story about them having saved the world if they all know that such a thing never happened. The yaks may be a prideful nation, but they certainly aren't liars who have to make up stories to boost their ego or reputation. Their great sense of pride definitely developed from some great deeds as well, especially considered that they survived for centuries, maybe even millennia, without help by other nations.
If the yaks indeed defeated some great evil a long time ago and saved the world that way, this adds more points to the conclusion that they possess magical weapons that gives them power in combat that is much greater than their physical strength.
Their pride, though, is also probably their greatest weakness. When Prince Rutherford told Pinkie the story of how he fell into a hole as a young yak and waved at his family without receiving any help, this reveals that the yaks, while living together in a mostly civilized society, are harsh to themselves and their friends and families even, refusing to help one of their own kind with a problem or in a dangerous situation.
This would probably change in a situation of war or if they fight against a mutual threat, but in hard times for their kingdom, accepting help or not could be a decision between their survival or their downfall, depending on which kind of crisis strikes them.
A thing I was wondering about while watching the episode, as I already hinted on further above, is that we haven't seen the castle of the yaks anywhere, even though we got a few nice aerial views of Yakyakistan. There were a few spots that were off-screen and that we couldn't see, but those aren't big enough to have room for a whole castle.
The castle seems to be somewhere else and not located inside the walls, for which their pride could be the reason as well. With how much the yaks pride themselves on their strength and self-reliant culture, it does fit that their castle is at another location, to present rulers from other kingdoms something great and majestic, instead of a bunch of clay huts, to appear imposing, powerful and, maybe, even threatening to other nations and kingdoms.
The yaks might fear that other kingdoms wouldn't take them seriously if they would show them their easy way of living, so it would make sense for them to keep that hidden from visitors if necessary.
"Not Asking for Trouble" is one of those episodes that seem to not have much to offer on a first glance, but reveal great things if looked into them on a deeper level. And while I would have hoped for a more exciting episode to serve as a mid-season "finale", I'm happy that we finally got a lot more insight into yak culture, after waiting for this for two whole years!
