Gue

Its back! Gues are semi-rare enemies that attack by spitting acid at you that inflicts posion and leaves a puddle of toxic water. These enemies should be dealt with quickly before there is toxic water everywhere. Gues can spawn in toxic biomes, sewer labyrinths, and human labs. They have a 50% chance of dropping gue eyeballs and always drop acid when killed.

Orgin
None! Gues do not come from any video game, movie, book, etc.
