Dungeon World Monster: Tramble the Traveler

Tramble the Traveler is a wandering nomadic trader with odd and valuable wares. Tramble has no use for your silly metal discs and instead conducts business by barter, and always rolls every 'R' they say. Tramble is of an indiscernible race, and though they are roughly the size and shape of a halfling they will simply giggle at any notion of them being one, stating they "Were there when the halflings crawled out from the primordial broth." One of Tramble's eyes always seems to be following you, even if someone else claims it's looking at them, not you. Their clothing matches in neither color nor style, and indeed perhaps even the world they find themselves in and changes any time you aren't looking, but the one thing that is constant in their apparel is a dusty pinkish fanny-pack they produce all their goods from. The fanny pack is seemingly endless and holds any number of non-living objects that can pass through the opening, and when it is opened a large cloud of dust billows out of it. Instinct: to barter with any and all
