I received the below mentioned toy for review, all views and opinions are my own. See Disclosure.
The Happy's pet requires two AAA batteries which are not included and you will need a screwdriver to install them. Once your pet is ready to roll a smooth hard flooring works best. Our kitchen worked the best for Thunder, however a few times the ball would roll through the doorway Thunder had no problem crossing the bumpy thresh hold. As with any toy with powerized spinning wheels be sure to keep The Happy's away from your hair and shaggy carpeting. I explained to the Booper to never put Thunder near his hair and it hasn't been an issue.
The Happy's toy pets and accessories are available at the following retailers; Toys R' Us, Wal-mart, Target, Justice and Radio Shack. The perfect gift idea for the holidays or any time of year for kids!
