The Happys are interactive faithful and furry friends who really play. They interact with each other as well as their owner using Infrared Technology. They have a range of movements and sounds and even follow their owners and perform special tricks. Using the magic of IR technology, your pet will move towards the Rockin Playground playset. Watch your pet have a pet pile up with their Wobble Toys or dance. Press the button on the playset to watch your pet stop and perform a silly dance or pounce into a pet pile up. Requires 3 x AAA batteries (not included).
