Ding-a-ling. In the Kullerbü ball track of the same name by HABA, Ball Paul zooms in and brings two bells that ring. But first, he has to navigate a thrilling steep curve, where he gains plenty of momentum. Then, Ball Paul races down a straight track and over the bell seesaw, crashing through several dominoes at the finish line with a bang. It's a huge amount of fun - and that's why it's time for another round of rolling excitement with Ball Paul. The Kullerbü ball track Ding-a-ling by HABA is perfect for budding builders aged 2 and up: even the setup encourages creativity and fine motor skills, while playing enhances observation skills and a spirit of experimentation. A must-have for every child's room. Included are: 1 bell seesaw, 1 steep curve, 9 connecting elements, 1 wave curve, 2 straight tracks, 1 ramp, 1 starting stone, 4 pillars, 1 Ball Paul, 1 effect ball, and 3 dominoes.
