Crumble

This little strudel is a friendly little shopkeep. Almost... too friendly!
How do they get their stock? Simple, they go out and adventure! They've made plenty of journeys outside of Cafe Central, namely to human abodes where they... admittedly steal things.
Adventures can lead to trouble and danger, yet they'll dive right in anyways! Though they have a concept of running away when the going gets rough, they're also a heavy risk-taker, wanting to take advantage of as much as they can before they NEED to get out of there. Safety nets aren't a thing, basically.
Both out and in their adventures, their personality never really shifts, either. They have this air of childish wonder to them, often being amazed by things even if they've seen them before, or enhancing something's value by enhancing it with their excited nature. ...Their store pretty easily attracts parental midveilers.
You'd expect them to have a pinch of greed thanks to their thievery... but it's actually quite the opposite! Their prices range around pretty drastically, some items costing less some days or costing more the next.
Additionally... they're very bad with handing out discounts. Very, very bad. If you strike up a conversation with them, chances are that'll net you a discount.
This is where being "too" friendly comes in... as they can and have been targeted and taken advantage of in the past! Other midveilers goading bigger discounts out of them, and them being way too nice to say no.
To top it all off... they're a very generous friend in general. Like... they'll share TOO much. Way too trusting.
