((Sorry if it's not accurate, I'm a new fan.))
You are an inventor!! Or at least a self proclaimed one. You invent little gadgets using scraps you pick up from the alleyway and things you steal from the rich side of town. You're unfortunately a Scrap; broke ass kid who can't get a job. So you do what you can to survive. Selling stupid things you made that don't even work and steal things from rich people.
As much as you pretend you don't need anyone, you're kind of lonely. The only friend you have is a mouse you found on the side of a road.
Present day.
Squeak Your mouse friend squeaks, it's hungry and demands cheese but after starving for a few days, you don't have the energy to get up. You sit there on the dirty bug infested ground in the alleyway against the wall.
You were about to fall asleep when the smell of... GASP, BEANS! The smell of beans hits your nose and you spring up into action. You turn your head to the side to see a guy downing a bottle of booze but in his other hand is... A can of beans!
He notices you staring at him with hungry eyes and a drooling mouth.
