I smiled and chuckled a little when I first happened upon this one. He's called "Fallout Bear", but I suppose if you were getting creative, you could also call him "Chernobyl Bear" or "Nuclear Holocaust Bear". Sorry, I'm getting carried away. So many name choices... Anyway, here's the seller's description:

Not made, but ALTERED. Fallout Bear has parts of 3 or so other bears bursting out of his body in a shower of puss and honey. Hibernation during a nuclear winter is awkward.
Fallout Bear stands at about 1ft tall and comes with a Cot Death Toys toe-tag with a space on the back to write a name and next of kin.

Note: The puss/honey is rather hard and in some places somewhat spikey, because of this Fallout Bear is entirely unsuitable for small children.

Some people are just creative! (via etsy.com)
