The Spinosuarus is fully articulated at the joints and his mouth even opens. He's suitably menacing looking and satisfyingly chunky and hard wearing. He can stand up securely without wobbling. The only thing you'll find difficult is explaining why there are human beings in the same kit when everyone knows (even my just 4 yr old son) that dinosaurs were extinct before we came around! And it's unlikely a 4 yr old will have seen Jurassic Park just yet... Ah well, bit of artistic licence there from the designers. Highly recommended anyway, in fact all the Playmobil dinosaurs are - we have the whole set due to one very lucky birthday boy.
