A competition for clever new inventions gets everyone excited.

Somewhere by a great sea stands the small village of Gadgetville, where inventing all manner of domestic gadgets is held in great esteem. The villagers organise an annual competition of new inventions. One of the most famous inventors in the village is Oskar, the father of the energetic puppy girl Lotte. His primary rival is Adalbert the rabbit, whose wife also participates in the competition with all her heart. Victory would be important to their family and would bring honour to the entire rabbit clan.
