A marmot recounts being born in an Alpine crevice, captured as a youngster by a village boy named José, and brought to a valley cottage where it adapts to domestic life. It offers a physical description, learns tricks, shares food and affection with José and his neighbours, resists sale to travellers, and enjoys popular attention before confronting the distress of being promised to another child. The narrative blends playful episodes, simple moral reflections on obedience and gratitude, and charitable purpose, framing the animal's memories as an engaging, didactic tale for young readers.
