Ferdinand, a little bull, prefers sitting quietly under a cork tree just smelling the flowers versus jumping around, snorting, and butting heads with other bulls. As Ferdinand grows big and strong, his temperament remains mellow, but one day five men come to choose the "biggest, fastest, roughest bull" for the bullfights in Madrid and Ferdinand is mistakenly chosen. Based on the classic 1936 children's book by Munro Leaf.

The story of "King Lazzarone" Ferdinand I of Bourbon whose pastime was to neglect the government and disguise himself as a poor man and turn to the infamous city premises in search of love adventures. With the De Filippo brothers to complete.
