SCP-1356, or "Rubber Ducky", is an upcoming SCP in SCP: Unity that will be added in an as of yet unannounced update.
SCP-1356 is a small bath toy, resembling one of several generic "rubber duck" designs. Tests indicate that the object is made of plasticized polyvinyl chloride. It is designed to emit a sharp "squeak" when squeezed.
When held by a human subject, the object appears to displace liquid water. If a subject holding the toy attempts to enter a lake or pool, for example, they will find that all liquid within an area extending approximately 152.4 x 81.3 x 45.7 cm from the body disappears.
SCP-1356 is not currently in-game
