The Gold and Diamond Encrusted Harmonica Store is a minor location in 12 Oz. Mouse.
It is a store full of gold and diamond encrusted harmonicas. It only appeared in "Star Wars VII", the Rectangular Businessman goes to the store so he can buy a gold and diamond encrusted harmonica. At the harmonica store, the Rectangular Businessman stares down a row of gold harmonica's filled with diamonds. Eventually, the Businessman returns to Shark's car, that still hasn't started. The purple square didn't even buy a harmonica, for unknown reasons.
The store's interior is the only thing of the store seen in the episode, the entrance is seen with windows saying "Harmonicas" backwards in yellow, a door is seen, a white block shelve of harmonicas is seen in the background, there is a large white background full of harmonicas, there is a large row of harmonicas seen, and it spans up to the clouds, and an airplane can be seen moving in the air, implying that the harmonica store is very large. Nothing else of the store is seen.
- This store's exterior is never seen in the episode, as nobody presumably owns it, and the store is never seen being destroyed by Shark in "Eighteen." The store's fate is unknown as its only exclusive to the episode "Star Wars VII", nor mentioned ever again after this episode.
- The song that plays in the store is called Beach Parade, which was composed by Armando Trovajoli.
