Andy over on HUKD has spotted a really lovely deal for the kids. It's a jumbo floor puzzle of the very hungry caterpillar! You can nab it for only £3.99 @ Play.com, including free delivery.
This jumbo floor puzzle says it is for ages 3 plus, so if that is appropriate for your little one, then time to flex the credit card!
The very hungry caterpillar is a hugely popular kids book... I think I even recall reading it when I was just a toddler. It was first published in 1969 - I didn't realise it was quite as old as that until I googled for the wikipedia entry!
And by the way, if you happen to purchase the book itself while you are over on Play.com, you can get 10% off the range of toys, including the floor puzzle mentioned above.
