Mine

The Mine, also known as the Cragsters Kingdom, is a region on Planet Popstar. It is a network of tunnels and caverns deep underground, but there is also an above-ground area with small houses, mailboxes, and giant boulders. It is where the Cragsters reside.

Appearance
The Mines have a flat golden landscape with giant boulders with multiple holes and chunks of gold on top. The giant boulders are stacked onto each other with multiple mailboxes with more than one mailbox connected to the pole, and each mailbox is a different color.

Trivia

 * The mailboxes and flags are some of the few non-rock elements of the habitat.
 * The underground mine has never been seen in the animated series. Rather, scenes taking place in the Cragsters' land is in the town above ground or, occasionally, in simple underground layers.
 * Digging entirely through the Mine leads one to the Mountain City, as seen in Electrorock.
