Given that I never posted this, and that I usually slap filters onto art pieces depending on the setting, here is the fully, regular colored reference for the Ultimate Rig-Kid himself.

Riggs is a fourteen-year-old who finds himself wound up in the town of Briddlyberg, a town between Burbank and LA. He and his two siblings, Riggy and Riggette wind up with powerful mallets after a transaction gone wrong. They use their new mallets to defend the town of Briddlyberg from the threats that... threaten it I guess.
