About 7 or 8 years ago, I found the most amazing advent calendar (in Poundland of all places!). It was a magic cube, one of those which you can fold and unfold to create different scenes. It had a "mouse" theme, I believe, windows and doors which opened and a tiny little book.
Unfortunately it got misplaced when we moved house 
I'm desperate to replace it, and was wondering if any MNers might be able to help? To even know the name of it would be amazing (and help me narrow down these searches)!
