“The shop is called The Three-Story Rat Hole, although it is only about one and a half stories tall. Three completely separate buildings have collapsed into one another: a former bakery leans into an abandoned tailor's shop, which has folded sideways into an old watchman's cottage. Their roofs overlap like badly stacked cards, their staircases lead into closets, and rainwater travels through the ceiling in a route Pindle proudly calls the 'indoor river.' Every room is crowded with crooked shelves, hanging baskets, dangling signs, and towers of cheap goods that sway whenever someone sneezes. The proprietor is Pindle Squeakwhistle, a cheerful ratfolk commoner with a green waistcoat, enormous spectacles, and a tail wrapped in colorful ribbons. Pindle buys abandoned household goods, failed inventions, adventuring leftovers, and anything described as 'probably still useful.' He keeps meticulous records in a ledger that is only legible when held upside down. His sales patter is fast, theatrical, and deeply untrustworthy in the harmless way of a carnival barker. He refers to every customer as 'valued surface-dweller' and insists that all purchases come with a free emergency button. The shop's staff consists of Pindle, three messenger rats, and two unusually well-trained giant rats that sleep in a basket labeled 'Do Not Put Rats Here.' The messenger rats carry price tags around the store and occasionally switch them. The giant rats are friendly unless someone touches Pindle's spectacles, the royal tinderbox, or the portrait of Old Crumbtail. A successful DC 10 Wisdom (Perception) check notices that many shelves are braced with furniture from the other two buildings. A hard shove, thunderous spell, or failed attempt to climb the stacked merchandise may cause a harmless but noisy collapse, creating difficult terrain in a 10-foot square until cleared.”
