Welcher is a minor character on Edgy Oobi.
He is a talking hand who washes hands with Uma in "Uma Gets a Job!" for a price of $50. However, he breaks his promise and only pays one dollar, so Oobi (as his alter-ego Pimp Daddy) chases the welcher down for his wallet. When the welcher doesn't comply, Pimp Daddy takes him out and buries his remains in the yard.
He is an average talking hand with blue googly eyes, which are suspiciously similar to those of the judge from earlier in the same episode.
