Squirrel and Hedgehog is a North Korean animation set on Corneria approximately 400 years before the Lylat Wars, in a conflict between Flower Hill Top, the Weasel Empire and their ally, the United Wolf Republic.
This is the standard issue side arm of the Flower Hill military.
The Design I made up on my own because, the pistols in Squirrel and Hedgehog appear generic and simplistic. I'm not perfect at drawing but, it probably looks more realistic than what is shown in the show. I made up the name by typing random letters and numbers. Yuengh doesn't mean anything really but, it is suppose to be in one of the languages of the world in Squirrel and Hedgehog. It may not be from Flower Hill language because, it is possible that most Flower Hill weapons are imported from other countries.
