There are a total of seven pet accessories that are available in the shop at a time, and the available accessories change every Tuesday and Saturday at 9 a.m. Pacific time.
The Hat Shop takes the appearance of a blue tug boat with a large anchor, due to when it was underwater. It has three windows (one at the top and two high-pressure windows at the bottom) and a walkway leading up to it.
The interior of the Hat Shop is actually a separate island where the tug presumably sails to when a player enters it. The island has two shop stands where accessories can be purchased from with palm trees and various sea and pirate-themed decorations spread throughout the island. A shipwreck can also be found close to the island. There are platforms that display 6 types of pet wear each rotation. They are modelled on a mannequin resembling the dog. At the far end of the island, players can find a throne-like chair. Resting on this chair is a mannequin, resembling the pet Dog, wearing the ultra-rare accessory available at that time. There are 7 pet wears that are displayed at each rotation
- It is the first building to have a live event for its release.
- The throne that the ultra-rare pet item rests on shares its model with the Throne Stroller, but without the wheels.
