SCP-066, also known as “Eric’s Toy” is a paranormal object contained by the fictional SCP Foundation.

It is a small mass of yarn and ribbon, capable of its own locomotion and paranormal abilities. It can create objects, make sounds, and make changes to the ambient environment around it. These were usually very pleasing and childplay-like events, but became more bizarre and hostile after the foundation performed tests on it.
