I'm selling a set of dinosaurs. The largest Tyrannosaurus Rex is from Toys "R" Us and is inflatable, making it puffy. Some make sounds when batteries are inserted. (I haven't confirmed if they still work. They did when batteries were in them, but it's been a while since the batteries died, so please understand.) There are what appear to be: Triceratops Stegosaurus Dimetrodon Spinosaurus Allosaurus Raptor However, I'm not very knowledgeable, so the details are unknown. These were used by a child. Some have paint chipping. They are used items, so please refrain from purchasing if you are concerned about minor details.
