Or… If you have a suitably warped sense of humour you could use Pengzilla. It and other stupidly deranged flightless nightmares are in - PHoD Rubbish Penguins. I personally gave a Red Dragon the Pengzilla appearance and now it gives the appearance of radioactive breath with a Godzilla roar.
The actual modelling work is some heavy lifting but you could probably find someone suitably willing to monkey with photoshop to give it a higher resolution texture, if the model itself isn’t terribly bad.
