Mimic

 I'd say Mimics exist in the lower echelons of likeability with other creatures such as Rust Monsters, mainly due to them being used as a very adversarial tool along the lines of "ha, gotcha!" by many GMs. Of course, given its toolset, it is of no surprise to anyone that the mimic is typically deployed more so like a trap than an actual creature.

That is the most obvious and easy approach. But we are not here for the obvious and easy, are we? RAW, the mimic can only appear as a medium object—but it can be any object. Despite being portrayed as pretty much mindless, mimics do possess a considerable amount of intelligence (score of a 10 is higher than a lot of animals and beasts in the book), so what's to say they shouldn't use it? And why couldn't a particularly tricky one get very big and pretend it's, say, a house?

Hook 1 (Max) - Galvanni's Gift

An announcer in fine robes shouts in the middle of the town square.

“Master Galvanni’s magnificent adaptable armor! Get yours today, don’t wait! It can do anything you need! Change its size to fit your chiseled physique, cover your nostrils from poisonous fumes, shift its color to blend into surroundings, create a nifty little backpack should the need arise and so, so much more! Visit Galvanni’s workshop to set up a visit today! You won’t regret it!”

*You might regret it.*

                        To that end, he has perfected a very uncommon "hunting" strategy—his preferred disguise is that of a single golden coin. He will often travel for a while in the possession of an adventurer or wanderer until eventually revealing his true form, giving his earnest and nuanced review of locations visited before finally consuming his increasingly confused victim.

Hook 3 (TJ) - The Fence

When it comes to disposing of ill-gotten goods in Millstone, the underground knows that there's really only one place to go. One would be tempted to think that farming communities don't have much in the way of crime or the need to offload stolen items, but that betrays an outsider's misunderstanding of what it means to have a centralized milling operation. Millstone's strategic positioning on the widest and fastest part of Logan Creek is no mistake. Farmers from all over bring their grain to Millstone for its expedient and affordable milling services.

The nefarious underground may not have the same economy of scale as larger operations in major cities, but it is certainly profitable. And no one makes more profit in Millstone than The Fence. First-time contraband foisters may think that their contact is called "The Fence" because of what they do—fence stolen goods. When they get to the meeting location on the north side of town and the posts and beams begin to warp and tremble, they're quickly proven wrong.
