SCP-729-J came to the Foundations attention when Dr. Hessen was being chased by SCP-106. He had managed to trap her in her office and prepared to kill her before he saw SCP-729-J. SCP-106 had then started staring at it while also backing away from it with its middle fingers raised. After he reached the end of the hall, he rematerialized back in his cell, and many of the researchers who witnessed the event were found huddling with SCP-106.
In it's testing logs, it is shown terrifying many of even the most powerful SCPs such as SCP-3000, SCP-076-2, and SCP-049. At one point, it even killed SCP-682.


Appearance:
SCP-729-J appears as a soft toy of a yellow marshmallow bunny. It is supposedly made out of polyester fiber but a researcher theorizes that it was made out of the devil's couch stuffing.
