We'll need it just because that's freaking awesome. I totally forgot about that, my stepmom did that for my sisters and brother and me. Guess who never won. XD
Yeah, I think he'll be okay about it, we'll just have to tell him how special and important it is. If that doesn't work, plan B is it's his special duty to guard the tree and make sure nobody knocks it over, breaks it, or otherwise messes with it. Plan C - get him a special climbing tree.
