From the model description:
The R/C Wooden Puzzle Dinosaurs go one better and add movement and sound to this classic dinosaur format. First you must assemble of course, but once you've jacked in the included motors and electronics you're ready to rumble. Not only can you control your dino's movements via remote, he (or she) roars and reacts to sound.
Here is the link to these two wooden mechanical dinosaurs with remote control.
