A 2cm or 5cm border should be will be fine, normally when I have my EMO dancing, I make sure he is dancing in the middle of the table, and not on the edge of the table, as he will certainly fall off as his feet sensors don’t work when he is dancing. So if you ask EMO to dance just make sure he has enough room to dance and he is away from the edges of any table before you ask him to dance.
If you are making a playground for EMO on your table take a look at some suggestions here from this post:
I would personally create a playground away from the edge of any table, so even if EMO fell out of his playground, he will fall on the table and not on the floor. I hope that make sense.
