This is Adalbert’s first invention. When Adalbert the Rabbit was a young inventor, he desperately wanted to impress the rabbit carrying a suitcase, so he asked Theodor to visit him to present his first invention. Theodor brought along some more important rabbits and everybody came to admire Adalbert’s invention. But unfortunately, the invention did not work. Despite its groaning and moaning it simply refused to turn on. Then Oskar lent Adalbert a little bit of electricity and the invention roared and turned on. The roar was such that it knocked the important rabbits’ socks off, and this is how the new invention got its distinguished name: tram!
