Firesaurus rex

Late one night, while having a bowl of spicy hot noodles and watching a marathon session of the Hobbit, Dr Wu suddenly had the idea to create a unique cross of a dragon and a T-rex. Unfortunately, as the new hybrid was hatching the lab roof was being repaired (after major damage from a new pteranodon) and the hatchling escaped never to be seen again. Some legends say that you will find it in a mountain of gold.
