Pipeyard

Pipeyard is a region which connects from Industrial Complex into Shoreline, Subterranean, and Sky Islands. It consists of various tunnels, pipes, and flooded caves, with a few more open spaces near the surface of the region. Most Slugcats can enter it without issue.

Overview
Pipeyard serves as an alternative to Garbage Wastes with additional region connections. It has generally more conventional of enemies making it easier to learn its mechanics, but many of its paths are one-way only, and the region is infested with centipedes, making it one of the few locations to have overgrown centipedes as survivor.

Sump Tunnel
A region that can be summed up as the underground parts of Shoreline but with the level design of the lower parts of Drainage System, connected to the rest of the region by dark pipes and flooded cave systems. It appears to be almost completely empty in terms of creatures, with only a few snails and jetfish.

Trivia
The region has a notably large number of Cyan Lizards as the Gourmand.

The song that plays in the Sump Tunnel subregion is a remix of an unused song found in the AGJ album, which went by the name SubSubSub.
