Though Bubi, a white Welsh pony, has only lived at the horse farm for a few weeks, he is already causing several problems for friends Tine, Ina, and Alex. While the messes he makes are annoying to clean up, and his gluttonous appetite can be a bit of a bother, the girls would be happy to ignore his flaws, if only they could find him. The pony seems skilled at disappearing, and locating him may be the least of their problems, if they cannot figure out how he keeps escaping.
