Part 1
Once upon a time, in a land far away, there lived a mongrel with no identity. The mongrel was dying to have an identity. So he decided to set out on a journey to find a 100% heritage.

But the world was a large place, so the mongrel split into two on his journey. One mongrel went to the East, and the other went to the West. The monster who went West came to a German village.

"Mr Blacksmith, please give me your heritage, i'm also 1/8 germanic"
"I can't give someone my heritage"
"If you give me your DNA, I will jump into your stomach and make you very strong in return."
"Really? You'll make me stronger? Okay, you can have my identity"
And the mongrel went inside the blacksmith's stomach.
The mongrel became Otto the blacksmith. Otto was the strongest man in town. But one day, "LOOK AT ME, LOOK AT ME, THE MONGREL INSIDE ME HAS GROWN THIS LARGE."
The hungry mongrel ate Otto from the inside. The mongrel stayed inside Otto for too long, he wanted McDonalds, but there was none in Otto's stomach.
The mongrel went back to a mutt without an identity.
