In an ordinary household live six extraordinary little pets—the resourceful Kexin, the proud and beautiful Shasha, the humorous and devoted Tang Yi, the master mimic Congcong, the erudite Muhei, and the "all-capable" Diandian—affectionately called "Pet Treasures" by the family. They live happily together with their grandmother and their young owner. However, deep in their hearts, they yearn for a more thrilling and adventurous life. Finally, seizing a chance opportunity, they embark on a journey to follow in the footsteps of Marco Polo and travel the world. Along their expedition, the Pet Treasures encounter many amusing and strange incidents. Time and again, they face perilous situations, only to overcome them with ingenuity. Being kind-hearted, they often extend a helping hand to friends in need. More often than not, they rely on their own strength and wisdom, using their wits and sticking together to navigate through countless challenges.
