We purchased the Drop and Roar Dinosaur for our son last year after Christmas from Walmart for $19.99 on clearance. This product is still sold at other stores and can be purchased from Amazon for 88.99! I think the price we paid was good deal and I would have paid as much 30.00 for it; however, I would NOT pay $89.00 for it.
This toy is part of the "Roll-a-Round" line from Fisher Price. The balls that come included with this toy are clear and have small dinosaurs that move inside - one looks like an egg cracking open with a small dino in it, one has a dino that spins, and one has a dino moving freely inside the ball. Other balls can be purchased and each one is similar - they're clear with animals, objects or noise makers inside.
The dino has several openings to drop the balls. When the ball is dropped in the holes, music is played and lights twinkle. The dino will roar some of the time when you drop the ball in the hole closest to his head.
This toy is recommend for ages 6 months to 2 years. My 18 month old son will play with this toy, but he does get bored by it easily. When he was a just a little younger (12-15 months) he would play with it for quite some time.
It is a cute toy. If your child likes to play with balls, I think this would be a great toy for him/her.
