Cavelinger (low light version)

A Cavelinger is a creature that lives in caves and abandoned mines. They eat berries and sometimes rotten flesh they find laying on the ground.
Cavelingers live in packs, crafting tools and basic homes to keep themselves safes in huge caves.
Cavelingers always have a huge gem sticking out from their body, it serves a radar to see better and travel with more ease trough caves.
Even though it's not a rule, the cavelinger with the biggest gem tend to lead their respective groups

This specimen is a low light variable, they sometimes wonder in the surface in the afternoon and live in not well lit regions of the cave systems.
