Meet my fish man I was talking about in this: https://sheezy.art/spacehyena/persona/asos-adopticoms/gallery/this-fucking-guy-again-art-trade

He's a totally normal human, yes ma'am. He kinda just hangs out around Gravity Falls trying to pretend to be a human. Which includes trying to buy stuff. Unfortunately, he doesn't understand money, o he tries to pay for things with fish with dudes painted on them.

[Image ID: Two fullbodies of a greenish fish man in a white t-shirt. They are identical, aside from one having a mustache drawn on it. Text on the background reads 'Raphael 'Raph'', 'fishman', 'upstanding citizen', and 'wears a fake mustache'.]
