Buddy is a hilarious, four-legged bundle of joy! You can have a blast making him sit, walk, and even beg for treats. But watch out – if you neglect him, he'll let out a bark to remind you he's there. Whether you want to take full control with a remote in any direction or program up to 40 actions, Buddy is up for the challenge. Just remember to shower him with love!! Bring Buddy with you and play everywhere!! The robot charges with a USB. The controller works with two AA batteries. Batteries not included.
