Toys and games just got a lot more interesting with this Electronic Pet! Based on my observations this will be a huge hit with any dinosaur-loving kids out there .The Spinosaurus` movements are impressively realistic, and its sound effects are sure to spark plenty of imaginative playtime scenarios. One downside may be that it requires batteries, but the hours of entertainment it provides are well worth the extra effort. Overall, I highly recommend this toy for any budding young paleontologists out there..
