Rudy's BFF, a painting robot, he/him, blue, 60 years old

He's chubby because that’s where his paint tools are, mixes paint by vigorously shaking. Rudy found him one day in an old lady's house. Top of his chest above his smock is a flap used to dispense paint. He was originally one of many robots designed to paint buildings. ("think Roomba but friend shaped"). He was abandoned because his batteries died and he just spent time asleep in the garage before Rudy found and charged him. He's more self-aware than an average robot of his make.
