I am looking for someone to help me with identifying a show that use to be on in the 80s. I am pretty sure it was on PBS. All I can remember from it was it had a few people around this tree and they had this little box and when they opened it, it was a little TV and you turned it on with a key. I would appreciate anyone who has the answer Thank You

The only one I can remember with a little TV was Ovide. I don't remember a key or a box but the TV would pop out of everywhere. I didn't watch much of the show myself (could never find it in English) so I don't know if it ever was in a box with a key. Sorry.
