A long time ago, when monsters and ogres lived around the world, Zeus decided to make his son Hercules immortal so he could rule over Greece. But Hera, Zeus' wife, doesn't like the idea. Now, Hercules must prove he's worthy of being called a hero.

"Is this all there is to life?" thought the donkey, who was working as a tourist attraction for in the "Animal-Adventure-Park ", after his boss kicked him out. And because people again and again told him that his voice sounded lovely, he decided to make a career as a musician and go to Bremen. On his way, he met a dog, whose fate was to spend the rest of his life in the animal asylum, because his old master had died. The dog was a great drummer, so the donkey asked him to come along with him. On their way they met a cock and a cat, who were also living in a desperate situation. Since they too were good musicians, it was only logical that they completed the band. And what nobody ever believed came true. After many adventures, they were finally on stage. Where? Of course in Bremen.
