Description
Principe Rospo is the enchanted prince at the center of the episode based on the Brothers Grimm fairy tale The Frog Prince. He appears as a large frog who lives near a well in the royal grounds, the form imposed on him by a spell cast by a witch. Beneath the animal exterior he retains the mind, speech, and noble bearing of a prince, and the story follows the classic pattern in which his curse can only be lifted through the help of another person.

His role in the story begins when a young princess loses her golden ball in the well. Principe Rospo offers to retrieve it, but asks in return for her promise to accept him as a companion, to let him eat from her plate, drink from her cup, and sleep in her chamber. The princess agrees without fully reflecting on what the promise means, and once the ball is safely back in her hands she hurries away, forgetting her part of the bargain. The frog, however, does not forget, and later that evening he appears at the castle gate, where his persistence forces the princess to confront her obligation. Her father, the king, insists that a promise must be kept, and she reluctantly allows the frog to enter.

His personality is marked by patience, courtesy, and quiet determination. He does not act out of malice or trickery; he keeps his word and expects the princess to keep hers. His motivation throughout is the desire to break the enchantment, which depends entirely on the princess honouring her promise and accepting him despite his appearance. The relationship between them develops from her initial repulsion to gradual acceptance. She fulfils each condition of their agreement, and when she finally overcomes her disgust and treats him as a companion and friend, the spell is broken. He is restored to his human form as a handsome prince, explaining that a wicked witch had cursed him, and the episode ends with the two reunited, signaling their marriage and his return to his former royal life.

His notable abilities are tied to the magic of the tale rather than to physical power. As a frog he possesses the power of human speech and the ability to travel beyond his natural surroundings, making his way from the well to the palace. His presence carries the enchantment, and the breaking of the spell is the central magical event of the story. Once transformed back into a prince, he regains his identity and his place at court, completing his arc from enchanted animal to restored nobleman.
