## Description

Make some noise, Hero hears everything! Build a unique sound-sensing robot from over 100 parts and learn about engineering and sound technology as you play and experiment with your six-legged robot friend. Thanks to its three directional microphones, Hero perceives and reacts to sounds, allowing you to control it by clapping your hands, snapping your fingers, playing music, or using the included castanet. Activate Hero to follow you around, respond to specific series of sounds, join you in a dance party, or even challenge you to a wild game of tug-of-war! With four different play modes, Hero provides hours of open-ended play and exploration. Hero's innovative design includes movable arms that disappear into its spherical body and a giant, illuminated eye for making facial expressions. The full-color, 52-page manual guides you through step-by-step assembly and includes a comic-book-style story about your new robot companion!

Review: Build it and enjoy it - We got this for our grandson and he loves it.
Review: Fun to Build, But Not Built to Last - This little toy robot is super cute and was really easy to put together—great for a quick, fun activity. The pieces snapped in without any trouble, and the design is adorable. However, it doesn’t stay together very well. Parts tend to fall off with even light play, which can be a bit frustrating. It’s more of a display piece than a durable toy, but still a fun build overall.

### ⭐⭐⭐ Fun to Build, But Not Built to Last
*by M***J on May 17, 2025*

This little toy robot is super cute and was really easy to put together—great for a quick, fun activity. The pieces snapped in without any trouble, and the design is adorable. However, it doesn’t stay together very well. Parts tend to fall off with even light play, which can be a bit frustrating.

### ⭐⭐⭐⭐⭐ Nice-looking and adorably stem toy
*by C***R on September 5, 2025*

The robot is very cute. We assembled it with my 9-year old son, and it was much fun. We could not figure out at the beginning, how different modes work, but in the end it worked and my son spend several hours playing with it! The plastic is sturdy and high quality, the instruction are well written. Would definitely recommend!
