Transformation is way tricker than on Mickey. I would have felt confident that a young child could easily transform Mickey but Donald is nore elaborate. He's something of a shellformer and folding his various little tabs and pegs in. It'll present no problem to anyone who's transformed a movieverse figure or Universe Sunstreaker but it may be worth noting for anyone planning to buy this for kids.
Hum... But then again, Donald is a complicated and complex creature himself. So this is only appropriate! :)
