What It Is

What It Is

Dinosaur action and adventure evolve into great play with the InterAction Roar 'N React Boris Tyrannosaurus Ultimate T-Rex. Nearly two-feet long, Boris is a fully articulated action figure, based on the character from the animated show Dinosaur Train. He says more than 70 dinosaur phrases and facts and includes several additional play features. Press his tail and his mouth begins chomping. Press his tongue, and he makes crunching sound effects. But watch out for his motion-activated stomping and his T-Rex-sized roar! What makes Boris really unique is built-in technology that allows him to recognize and interact with the other InterAction Figures in Learning Curve's Dinosaur Train line. (When put together, the figures will interact with one another, seeming to have a conversation.)

Why It's Fun

Combining dinosaur and vehicle play with innovative technology, Learning Curve's Dinosaur Train line features exciting and innovative products that provide a variety of opportunities for imaginative play. The InterAction Roar 'N React Boris is the flagship in the line. It brings the animated TV show to life and allows kids to embark on their own dinosaur-themed adventures. Mostly, though, kids will enjoy the noises and the phrases and the ways in which they can interact with a pal whom they mostly see on TV.

Who It's For

Young kids who are fans of Dinosaur Train are the ones who will get the most out of this toy.

What to Be Aware of

Two AAA batteries are required and included with the toy, but it never hurts to have back-up batteries. You'll also need a screwdriver to open the battery compartment. Per the manufacturer's instructions, do not use rechargeable batteries.
