I have googled but I'm not getting anywhere...
I remember a book I loved as a child about a snowman who hatched from a snowball kept in a freezer. I think the human family built a male and female snowcouple and then found the snowball. Possibly the baby snowman was called Flump. I was born in 1969 so the book could have been published any time from the invention of freezers until the 80s I suppose. Does it ring a bell with anyone?
