雕娜马 is a recently emerge holy beast of Internet, invented by Chinese, mostly Hong Kong(Golden) forumer. But it is in fact, a polite way of how Cantonese greet other's mother.
It can't be kept as pet, nor can it be tame.
Try to print it out as a post-card and send it to someone you admired. When they ask what is it you simply say the word diu-na-ma fast.
