Dimension Mites are tiny, insectoid monsters with the ability to eat their way from one dimension into the other, leaving a temporary portal between the two worlds. Because of this, the Troop uses Dimension Mites to return other captive monsters to the monster world.
Troop Notes
"The Dimension Mites are essential monsters needed to send the other monsters back into their world. Troops always breed a nest of these small insects and keep them at HQ. When a Troop needs to send monsters back to their own world, the Dimension Mites are released and then eat a temporary door into the monster world. The Troop can then push the returning monsters across the door and back into the monster world. Regularly used and considered 'friendly' to Troops across the globe."
