Capcom is now taking preorders for this Mega Man sleep set (yet only through its Japan site, for now) that will run about $60 once it arrives in the summer. It's a brilliant idea, and I expect to see a ton of these running around Comic-Con.
What might also be a good idea is to remove the Mega Buster before you fall asleep on it, as then your arm will probably go to sleep and you can't give yourself The Stranger with that thing attached to it.
