The khargra is a slightly less than classic monster from the first edition AD&D Fiend Folio. Khargra are creatures from the Elemental Plane of Earth (which itself seems to have gone missing in recent editions of the game) which burrow through solid rock like an earthworm through soil, but presumably without the beneficial effects to human agricultural efforts.
My interpretation of the khargra. The claws are molds of the hands of the "Squidhead"/Tessek figure from Return of the Jedi.
This is the rear view to show that the khargra has an anatomically correct anus. Baby's got back.
