Mr. Piggy was a human before. He ate meat all the time.

One day when he was eating meat, he suddenly felt a strange pain in his body... Everything happened in a blink. The organism was transforming!!!

Mr. piggy was screaming. He was transforming into a human-animal body!

One moment later he found himself as a Piggy Man!
After that, no one liked him. His wife left him, he was fired from work.
He was rejected and had no friends.
Until he met Meaty Man.
Piggy was accepted into the freak show because he seemed like a real freak.
Mr. Piggy wanted to tell people the truth - the dangers of eating meat!
But Meaty Man is the great deceiver and couldn't allow this.

He tortured Mr. Piggy and made him be quiet. Piggy had nowhere to go and couldn't be silent.  So Meaty Man threw him in the dungeon... Since then Mr. Piggy became his slave forever.
