I think the big dinosaurs should have limited articulation, due to how heavy they are. The rex should have a ball joint at the base of the skull, and another one at the base of the neck (where it meets the torso); the arms should have ball jointed shoulders, and hinged elbows. The legs should only be ball jointed at the hips, and non-articulated anywhere else, because those joints would wear out immediately due to the weigh. I don't mind if the tail is completely stiff, but if they want to give it articulation, it should have a ball joint at the base, where it meets the torso. Oh yeah, and most importantly, the jaw should open and close like Papo's t-rex.

The smaller the dinosaur gets, the more liberal the articulation can be.

However, I still think it would be awesome to have human characters! Blast what you guys think!
See the guy stuck under the t-rex's neck in the first photo? That's my first attempt at custom making Muldoon.

One more thing, the big dinosaurs should be made of the same soft vinyl that Bandai's Godzilla toys are made of. It would help a lot to make them lighter.
