Welcome - what you are describing is very interesting, and I can't help thinking that it's possible that play behaviours in reptiles often get overlooked, because we humans assume they haven't the ability to play.I think that physically a tortoise is rather limited in what it can do - but having watched Zola many times tugging at the hem of my trousers, then releasing it to watch it spring back , over and over - what else can I call it but playing ! And it is a game he invented for himself !
