Penny sometimes lies on her mat with a collection of favorite toys beside her. However, she lets us take them when we're tidying up. On the other hand, Louis the octopus at the Blue Reef Aquarium in Newquay, Cornwall, doesn't like it when the keepers take his toy away to fill it with treats. I love the picture of him clinging to his Mr Potato Head.
I followed this link from Boing Boing, who were sent it by Spluch.
