I found Patrick Star's house.

It’s in Austin.

This is the Austin Aqua Dome. It’s an aquarium shop. I don’t know how old it is, but it’s been around for at least 20 years. And it’s housed in a giant brown dome. For some reason.

Right next door is a BMW restoration shop, which always has a few intersting old BMWs outside.

The inside is a bit dingy and dark (it is dank, in the literal sense of the word) but it’s one of the most comprehensive shops for fish in town.
