A Hong Kong-based magazine released this video last week examining a very peculiar kind of pastry at a Sanrio pop-up shop.
According to Kotaku, the dessert dim sum is based on Sanrio character Gudetama. He's supposed to be a really lazy egg yolk.
Here's what the little Gudetamas look like.
If you turn them around though, you'll notice that they have butts.
And if you take a chopstick and stick it into the little pastry's butt and make a hole...
Here's a GIF of it in action.
Oh, also, it apparently can vomit custard too.
