More 🦕 dinosaurs!!

The largest one is the kind you can scan it and it does something? On the computer. The other three are hard plastic and would be very hard to destruct. The T. rex is 23 inches long and needs batteries. Has movable parts. The others are 10 to 7 inches long. The brontosaurus needs batteries. As far as I know these two dinosaurs that need the batteries were working before the batteries depleted. We had bought them for my grandsons.
