Let me introduce my alternative model built out of set 31019 - Tyrannosaur and Duck. Tyrannosaur features posable legs, claws, tail, head and openable maw. It is stable enough to stand on its two legs. When I've finished it I found out that most of yellow parts left and I was still able to build banana out of them. It looked very strange - tyrannosaur eating big banana. Then I've got another idea - I can build duck! ...and tyrannosaur has got proper dinner. :-) If you wanna build it there are building instructions at buildinst.sweb.cz
Great build! What makes it even more interesting is that ducks evolved from the same subgroup of dinosaurs that the T.Rex was part of. So it's eating its future cousin.
