No guys they are actually real claws off a small mud crab we have an abundance of ,about five minutes up the road from where I live .they are all over the place as well as soldiers,hermits,blue swimmers and more .i get a lot of inspiration from the creatures that our world has . I love real insects,there colours ,shape and pure alien ness to us.
Diggs, we do actually eat roo over here ,it's not that common but yes you can get roo meat in the super market and a lot of boutique sort of pie shops and restaurants and stuff you can get roo meat.
There is a shop just near us called Freddo pies that sell heaps of different types of meat pies,they have won a heap of awards for there pies and they offer crocodile ,Roo,emu and a heap more Aussie meat .
Ive tried roo meat it's quite tuff as you would expect but quite nice ,it's really nice as a jerky.
