PETA have created horrific Halloween charactatures of Mary-Kate and Ashley Olson for the latest anti-fur campaign.

Visitors to the animal rights group's site are encouraged to dress their favourite 'Trollsen twin' in the carcasses of dead animals in the form of 'butchered beaver boots' or a 'dead doggie shoulder bag'.

The website also gives visitors the opportunity to dress up like 'Hairy Kate' and 'Trashley' by printing off ugly Mary-Kate and Ashley Halloween-style masks.

PETA recently targeted Jessica Simpson for wearing a 'Real Girls Eat Meat' T-shirt and famously fell out with Naomi Campbell after she wore fur on the catwalk.
