I been studying and rescuing bats for more years than i care to count......For a bat mask, of truly bizarre proprtions take a look at spear nosed bats, mastiff bats, tube nosed bats, hondurus tent making bats rather than sticking to the vampire, or long eared like hollywood seems to. Also proboscis bats look like lichen.... Could Go for a face plate and nose covering eyes, sticky up ears with furry body over scalp wings curled under towards chin and tail and feet over the back of the head, that'll be a bit ..... different.A bat hat.... dunna dunna dunna dunna derThe chineese believe bats to be lucky indeed and on Bali they are worshipped as gods for good reason.....Good luck, There is nothing so precious as memories, except for those that make them...
