Max and Moritz the sweet ponies celebrate their birthday. Why not venture to celebrate a birthday horse, Bibi and Tina thinking and excited they immediately begin preparations ... Of course, it would be also nice if they could get the pony mom of Max and Moritz to the meantime, however, in the sullen Weidenhofbäuerin stands. That's not as easy as Bibi and Tina, the imagined, because the Weidenhofbäuerin not want the kids in the yard. And suddenly is Melinda, the cuddly pony mom getting sick. Now every second counts, because Melinda has a severe colic ... Can Bibi and Tina help?
Exciting and funny story to the end. Is worthwhile in all cases. The result is really great.
