Mochi

In the Hetalia universe, Mochis (also known as "Blobs") are strange senient creatures which resemble the personification of the nations in both appearence and personality.

They are apparently from the country they represent, as they speak their natives languages and can pop up their respective flags from their body, however, they can be found abroad.

Thier anatomy (as they are basically Japanese pastry) is very simple. They're all clear-colored and round in shape, as well as being very soft, flexible and expandable. Each one have different signature abilities.

The mochis doesen't appear in the linear story of Hetalia, they instead have their own spin-off series of strips (similar to Nekotalia), called Omochi and Otayuke, being Estonia the only nation featured. They have also appeared in some events, but they're mainly mascots for the Kitayume site.

Known Mochis

America

Mochi!America is the main mochi and the first one to appear. He is descrived as crazy (maybe a reference to America's hyperactivity, but the mochi is clearly, much more demential), but with no malice. Like his nation self, he has an enormous love for strong tastes, and if neglected, he'll grow to become obese. He is also prone to insult with profane words. He suddenly appeared in Estonia's house one day, and he started rasising him. He seems to be competitive and annoying towards other mochis, as he consider Mochi!Italy a "pig", Mochi!Canada "hairy" and Mochi!England "Gay". His level of insanity goes to the extent to believe that a lettuce can talk, that he is his father and that together they'll destroy the world.

He has the ability to shapeshift in anything he desires, he can shape himself as a hand, as a dog, as a pair of legs, etc. He can also pop up different things from his inside.

He has also shown the ability to evolve into a angelic, big-eyed, winged form, that seems to speak politely, but actually is hostile. In this form he can travel to the Mochi World.

This particular mochi is a main mascot in the Kitayume site and in the Bamboo Thicket bolg.
