PEAK players can earn the Well Rested Badge by finding and eating the Early Worm in the GLOOM biome. The badge is one of ten added with The Final Ascent update and also provides cosmetic-reward progression.

The pink worm appears on the ground in GLOOM, the fourth biome when starting from Shore, and can be eaten immediately after picking it up by holding the left mouse button. It restores hunger and sleep effects but not injuries; players should also watch for mist and enemies, as darkness can cause potentially fatal sleep damage.
