Legend has it that two magical creatures descend upon the human world during certain festivals: the Nian, endowed with positive energy and skills, and the other, a monster capable of destroying the world. Back then, Briar was the undisputed "Big Brother" of the forest. Until one day, an unexpected guest arrived. Her magical powers awakened different abilities in the two bears and Vick, leaving Briar the weakest. At this critical juncture, a villain appeared, causing chaos in the human world. The Nian failed to arrive on time. Seeking to become stronger, Briar fell into the villain's trap, triggering a devastating crisis. Therefore, Briar, Bramble, and Vick embarked on a journey to find the Nian.
