Picture book cinema: Tilda and Pony Törtchen - A pony is jealous

Tilda and her pony Törtchen are one heart and one soul - Tilda is even allowed to ride Törtchen when the pony feels like it. Until one day this boy from the neighboring farm turns up. While Tilda is thrilled, Törtchen's pony is rather suspicious of the newcomer. Soon Tilda is all about her new friend and the pony feels increasingly lonely. For children aged 4 and over.
