SCP-066, or "Eric's Toy", is an upcoming SCP in SCP: Unity that will be added in an as of yet unannounced update.
SCP-066 is an amorphous mass of braided yarn and ribbon weighing approximately one kilogram. Strands of SCP-066 may be taken individually and manipulated; when this is done, a note on the diatonic scale (C-D-E-F-G-A-B) is produced by the object.
After Incident 066-2, SCP-066 began to exhibit behavior highly inconsistent with its previous properties. SCP-066 now displays significant mobility, primarily in the form of being able to move tentacular portions of itself at very high speed. While SCP-066 is either unable or unwilling to use this ability for transportation, it will occasionally attempt to damage its containment by rubbing its strands against the side of the box, gradually wearing it down. This process appears to be unusually effective for the materials in consideration.
SCP-066 is not currently in-game.
