Sock Subway

The Sock Subway is Smellysocktopia's subway system.

On one occasion during Chapter 3 Part 3, the system ground to a halt as a Target Café grew inside one of the tunnels of the system. This led to many people in the café to get hit by a passing train, although they were unharmed thanks to cartoon physics. The café was eventually moved and made into a mini-Target Café inside Sock Corner station.

The stations were also once opened, during the same part, as emergency shelters after Squidward destroyed the town's mayonnaise in a fit of rage, leading many to think he was a jellien.
