Mashimaro

WIKI:

The original Mashimaro cartoons are full of toilet humour, and some of this is also to be found in the merchandise. Mashimaro himself is often portrayed with a plunger stuck to his head. In contrast to other hyper-cute iconic characters, such as Hello Kitty, Mashimaro is portrayed as a bit of a thug, who is not above using violence to impose his will on others.

Mashimaro (마시마로) is a Korean fictional character who resembles a fat rabbit, created by Kim Jae In (김재인).
