Cave 8

Cave 8 is a part of Cave 7, but is still its own dedicated cave system. It's officially called the 'Sinkhole Cave' although due to Cave 7 & 8 being mostly merged, and considered as one under the name 'Cave 7', Cave 7's sinkhole exit (actually part of Cave 8) is often called by the same name.

Unlike Cave 3, Endnight Games (developer) did not make Cave 8 more independent from Cave 7; Cave 3 was originally a part of Cave 1 in older versions before it was made its own distinct cave.
