Whenever I wear my squirrel jumper to school, all my friends shout "SQUIRREL!" We all watch too many kids' films. It's a great jumper, though.
On some internet clothes browsing, there are plenty of animals to choose from if you aren't really into squirrels. (If not, may I ask why??) Over half of this selection of jumpers I found in supermarkets - Tesco, Asda, Sainsbury's - so don't overlook the clothes section when you go grocery shopping.
