Oh wow, that does sound fun! I bet Totoro would love that, he's such a curious, active little dude - well normally he is, right now he's in blue and all grumpy about it, lol. But he's generally very active and I think he'd appreciate being a snake-in-the-box. That would be a really fun thing to have my niece help me set up, too, she loves my snakes and we could probably even find a way to make it a science project for her schoolwork!
