Towel Art

My sister posted some towel creatures on facebook last night (from her honeymoon) that appeared on the end of her bed.

 I want to say elephant but I don't think that's right

I thought this was very random, until I discovered this website. There must be some sort of towel art craze that I'm not aware of or I've been sheltered from until now. You can find some of these cute critters on P&O cruises and at Hilton hotels too.
