Trilexia

Trilexia were, according to Bernice Summerfield, "wretched things".

Benny and Jack McSpringheel were once imprisoned on a Trilexian Hunt Ship with at least one companion, who suddenly transformed into many small Trilexia seeking to eat them. However, Benny quickly activated an airlock, and the Trilexia were sucked into space before Jack even noticed. She attributed her readiness to her "spidey-sense". (PROSE: Adorable Illusion)
