MY ROBOTIC PET TUMBLING HEDGEHOG

Finally, an adorable robot! When kids assemble the 172 pieces, they won't realize they're learning about gears, motors, and sound sensors. They will realize that it reacts to different sounds. It will tumble, walk, spin, and bristle its spines in difference modes and clap sequences. Requires 4 AAA batteries.
 

For ages 7 yrs-teen, from Thames & Kosmos.
