The kretch insect was a scorpion-like insect that could be found in subterranean passages of Belsavis and Aargau. Kretches had six legs, two jaws, and a barbed tail. During the visit of Leia Organa Solo to Belsavis while she was searching for information about the children of the Jedi, she was attacked by one such creature and later threatened with a swarm of them by Irek Ismaren to help in her capture. The Jedi children, during their stay with Ho'Din Jedi Plett, were warned from straying into the crypts adjoining his home with the saying "the kretch will get you."
