Realistic dinosaur figure set, including Spinosaurus and Tyrannosaurus. - Type: Dinosaur figures - Model: Spinosaurus - The legs tend to swivel easily from the start. It also takes some skill to get the legs to stand properly. The mouth opens when you press the head. - Model: Tyrannosaurus - One figure has rust on the battery compartment and makes no sound even with batteries inserted. Batteries will be removed before shipping. Another figure has a part of its body that turns red when pressed. These were used by a child, so there is some paint chipping. Thank you for looking.
