Ugobe released with the Pleo a cute baby dinosaur last year and the company has not updated their offering for this Holiday. This leaves room for other toy makers to unleash their robot dinos, like Mattel who sends into the battle the ferocious looking D-Rex.
The Mattel D-Rex responds to voice and touch and can be controlled via bone shaped remote control. Commands include attack and obey. D-Rex is a ferocious yet loyal dinosaur with an independent personality. D-Rex is not nearly as advanced as Pleo in terms of movement, personality and evolution, but it is also far cheaper.
The Mattel D-Rex robot dino sells for $129.88 on Amazon.com. Pleo still sells for a rather high $320.55.

Another interesting dinosaur toy is the ride-on Kota Triceratops and the Fisher-Price Imaginext Spike.
