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 known unclassified documentation.

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.


To get... Feed a Black alert tribble the following...

Mycelial Tribble icon.pngCommon icon.png Blue Arrow (Left).png Sautéed Shiitake
  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 was introduced through a partnering of and STO. With the purchase of one of four qualifying "Large" Tribbles (The Triolic Tribble, the Gamma Quadrant Tribble, the Radan Tribble, or the Winter Tribble), you would also receive a code on a tag attached to the tribble which would allow you to claim the Black Alert Tribble in-game on any and all characters you desire. Additionally, a chanced-giveaway was held from July 15th to July 21st 2019 where eight winners received a Black Alert Tribble as well as an Age of Discovery Starter Pack (though this was limited to PC only). Since that time there have been subsequent TribbleToys giveaways and it's possible we'll be seeing more in the future.
  • It was available from the Groupees: Help the Boys and Girls Club of America! bundles from January 28th to February 4th, 2021.
  • The Black Alert can be bred to create the Mycelium Tribble - an "improved" version of the Black Alert, at the cost of one Lobi Crystal to purchase the Sautéed Shiitake. Of interest is the fact that the base tribble (The Black Alert) is not "Consumed" upon eating the dish, allowing both tribbles to be kept.
  • This tribble (along with the aforementioned Mycelial) has a different petting animation and sound than any other tribble currently in-game: video of the unique animation.
