Rat

I feel bad for Rat, so it's time to fix his lore.

A rat in the kitchen is a pest that poisons/taints the food with it's filth.

A rat in the home is a smart, affectionate, lucky charm. Course, that's only if you keep it clean.

A rat in reference of a person is someone who corrupts the home with filth, lies, manipulation, abuse, and because they are vermin, they won't stop eating. Instead of thinking of a snitch, think of someone who lies while switching between two people so they can get away with stealing things while the others are too paranoid to trust each other.

You better be grateful and give thanks to Rat. Without Rat, The World would not be here today.
