Cloaking Droid Trap

The technology that powers this droid is so advanced that many believe it must have come from another world. It utilizes a highly sophisticated cloaking device to blend seamlessly into its surroundings making it completely invisible to the unsuspecting mice that cross its path. Its single, menacing eye uses infrared vision to detect the heat signatures of its prey so while the droid can hide from others, nothing hides from the droid.

No one knows how it was built or by whom but the why is abundantly clear... it was built to be the perfect predator.
