There is another thread where a chaperone gave a child with SN a toy rat to keep them quiet. I read the thread and was appalled and yet comforted by the pictures of the rat. Didn't want to hijack that thread but it reminded me of Hartley Hare, who was a terrifyingly bad puppet in a kids show in my youth. The show was called Pipkins I think and included Topov the Monkey and a tortoise, whose name I can't remember.
Am I the oldest and/or most disturbed MNer? As, while Hartley terrified me he also brought joy to my heart because he was such a bad little shit! I think 70s kids TV may have been dominated by people on some sort of recreational substances to be fair.
