Caring for a sick imp

My son Miles has the flu! Oh no... He had a marathon sleepfest yesterday but managed to stay awake long enough to watch this dvd. I thought it was really brilliant, and I'm fast becoming a Hayao Miyazaki fan.
To cheer my son up a little, I managed to finish this little Japanese creature for him. He's too sick to enjoy it right now, but at least he went to sleep with his new little imp. From what I gather, this little character is the trouble maker of the bunch, so he (she?) is a fitting companion. I also found out that ragdoll in Japanese is "nuigurumi".
I heard about Aronzi Aronzo's delightful quirky critters from one my favorite Japanese eBay sellers because I almost bought this book from her.
If you're feeling adventurous today, you can check out the site in Japanese here and see the other characters.
