In the fifty-first year of the Mole calendar, in the beautiful and vast gentle land of the Mole's world, many magical creatures live. Among them are three major tribes living respectively in the Mole Himalayas, the Black Forest, and Mole City. The oldest plant spirit in the world, King Lam, is the master of the Black Forest. This ancient being possesses many magical powers and the mysteries of nature. No one remembers King Lam's age, which is older than all the ages of the Mole kings combined. Due to a misunderstanding caused by a forest fire five hundred years ago, it has long secluded itself in the Black Forest and has not intervened in the affairs of the Mole's world for centuries. However, some lucky little Moles have encountered some clever and adorable little Rams in the Black Forest. They followed the adventurous Moles back to Mole City and became the best spirit friends of the Moles.
