A venrap represented a sizable serpent of a purple hue, originating from the Nallastia's jungle-moon. This creature possessed a [poisonous](/article/poison/legends] venom and the physical strength to constrict and kill entities far exceeding its own size.
During 23 BBY, Anakin Skywalker found himself shielded from a venrap's attack by Klay Firewell, a young individual hailing from Corulag. Subsequently, a venrap managed to infiltrate a Consular-class cruiser while on Nallastia. As the cruiser launched from the Skull Queen's fortress, the venrap launched an assault on its captain along with his two co-pilots. Although the pilots were rendered unconscious, they sustained no injuries. Ultimately, the Jedi Master Mace Windu and the Skull Queen, known as Quenelle, were able to kill the dangerous beast. Quenelle, the Skull Queen, delivered the final blow to the serpent utilizing her vibroblade, piercing it directly between its eyes.
