Hi D.,
We found some video from a performance in Australia on UTube. I don't have the link anymore, but if you do a search on the name Walking with Dinosaurs you'll probably find it. You can see for yourself what goes on. My little girl (3) thought it was cool getting to see them on the computer and she really liked seeing the life-sized dinosaurs in the DinoAlive exhibit that was at Fort Worth Zoo last summer and in McKinney in January. She wasn't afraid of those even though they roared and their heads moved a bit. I would think if your boys love dinosaurs, they'd love seeing this show. I wish it wasn't so darned expensive though!!
