NarpsUK are giving you a chance to win a £20 Amazon voucher in a fun caption competition. To enter, go to this tweet and follow them, if you don't already, then tweet them with a caption to the picture (it's actually a very short animation) they link to.
You can enter once a day until the closing date of December 4th.
