Sonny and the Good Doctor

Sonny Hodgson is a drifter. Once a rising star in the track world, his career faltered after a bout with pica, and in particular, an obsession with eating rings, left him with blue skin from an acute case of silver poisoning. His closest friend is fellow drifter and disgraced doctor Ivan R. Bibic. When the doctor's not tinkering with whatever gadgets he can scrounge up or digging in the park for precious stones, he's more than happy to feed Sonny a steady supply of whatever "pharmaceuticals" he can get his hands on to keep him, both figuratively and literally, running.
