Battery operated - His arm moves up and down and he blows bubbles from a suprising location. He also makes very intresting noises, not for the meek! Bub requires 3 AA batteries which are not included but available if needed. We also supply you with a bottle of bubble solution, so you can Bub L Breeze right away. You won't need an air conditioner with Bub L Breezer. Great laughs, Great item!
