The Mycelium Tribble is a type of a tribble: a cute, round, furry creature that purrs when touched, and has a tranquilizing effect on most races.

This tribble is... was... Polygeminus grex stamets. Its journeys have changed it.

This breed was first discovered by accident, having suddenly appeared within the primary food stocks of the Corvan II mining facility. It was quickly quarantined and sent back to Earth for further study... but disappeared again during transit. The precise means of its transport is unknown, and matches no unclassified documentation.

This particular individual exudes an aura of almost impossible sagacity. It has somehow mastered the mycelial network and freely traverses it. Its motives are mysterious, its decisions beyond our understanding of space and time, its fur fluffy and soft.

Petting this sub-species of tribble has been shown to subtly manipulate the space-time continuum as it relates to the individual. Operation is recommended only for the most adventurous captains, and those seeking to discover new experiences.


Parent Food to obtain Mycelium Tribble

  1. When Black Alert Tribble was initially released, feeding him with Sautéed Shiitake would breed a Mycelium Tribble. Currently it can only breed Mycelial Tribble which doesn't come with a 100% extra movement speed buff.


  • This tribble (along with the Black Alert tribble) has a different petting animation and sound than any other tribble currently in-game: video of the unique animation.
