Product Description

Build your own adorable robotic pet Hedgehog! With the 172 building pieces in this kit, you can assemble a real robot that looks like a cute Hedgehog. The robot has a built-in sound sensor and is programmed to react to different sounds. After you build it, you can play with it by making different sounds and watching it tumble, roll, spin around, Bristle its spines, and scurry around. Clap once, and the Hedgehog will roll into a ball and tumble backwards. Clap multiple times, and the Hedgehog will count your claps and tumble as many times as you instructed with your claps. You can also get the Hedgehog to Bristle its spines and act in a playful way with different patterns of claps. The Hedgehog eyes light up with LEDs. By building the robot, you will gain experience in the inner mechanical workings that enable the robot to move how it does. Learn about gears, motors, sound sensors, LEDs, and the other components of these funny little pet. Approximate build time: 1 to 2 hours. Difficulty level: challenging.

Your Robotic Hedgehog

Before you can start playing and experimenting with your unique little pet, you have to build it! The kit comes with 172 building pieces to assemble your robotic hedgehog and includes a sound sensor which is located on the circuit board in your pet's head. It's this sensor that enables your hedgehog to move according to your clap commands. Like a real hedgehog, your robotic pet can run and curl up into a ball. Fortunately, though, the sound sensor enables it to listen to and follow your orders rather than immediately curling up when it feels threatened (like a real hedgehog would do). By building your hedgehog from start to finish and getting a good look at all of its components, you will gain experience in the inner mechanical workings that enable the robot to move the way it does. In addition to a crash course in sound sensors, you'll also learn about gears, motors, and LEDs (your hedgehog's eyes light up!).

The Manual

The full-color, 40-page illustrated manual provides highly detailed step-by-step instructions for building your robotic hedgehog as well as troubleshooting tips and explanations to get your pet working and moving smoothly. But the manual isn't just a set of assembly steps--it also includes some interesting scientific information and fun facts about hedgehogs and bionic robots.

Nuna, the Tumbling Hedgehog!

That's right! Your hedgehog has its very own comic! Embark on an exciting archaeological exploration with a bonus illustrated story that follows Tom and Izzy, two inquisitive young scientists, as they build Nuna the Tumbling Hedgehog while on an excursion to the Temple of the Gaaa!

Operating Modes

Mode 1

Mode 3

Tech Support

Mode 1: Roll backward and sleep

Your hedgehog is in Mode 1 when its eyes are glowing orange and green. In this mode, your hedgehog can accept the following commands:

  • Clap once: Your hedgehog will roll backward
  • Clap twice: Your hedgehog will roll backward and then stay curled up and fall asleep
  • Clap three times: Your hedgehog will wake up and unroll itself, ready to play!

Mode 2: Multiple backward rolls

Your hedgehog is in Mode 2 when its eyes are glowing green. In this mode, your hedgehog will roll up to five times in a row, depending on how many times you clap. Clap once, it'll tumble once; clap twice, it'll tumble twice; all the way up to five times!

Mode 3: Applauding for a backward roll

Your hedgehog is in Mode 3 when its eyes are glowing orange. In this mode, your hedgehog wants encouragement to put on a show! Keep clapping to cheer your pet on as it completes a roll. Don't stop clapping before the trick is complete! Otherwise it'll just stretch out and start walking, and the show will be over before it begins!

    Nice toy but breaks easy

    Nice toy but breaks easy
    Bought as a gift for my daughter, she was so excited. After spending over an hour to build it, she finally got to play with it. Not the easiest control, you clap to make it work. After the first day the peg that holds the gear that drives the wheels broke. Now I spent a hour trying to find a way to fix it then the button that turns it on and off isn't working right. Daughter isn't happy with it anymore because it keeps breaking. If it would work without breaking it would be a great toy but as is, it is only ok.
