The castle was now at peace and whole forest was experiencing a season of harmony and rest. Until that fateful day when the wolf awoke, and he began to assemble a new army. This time, Serigala, the great wolf, gathered the angry baboons from Mount Papio and the giant jacaranda bees to help him overtake the castle.

What happens to a castle stronghold when the residents become complacent, selfish, and lazy? What happens to a castle when the tower guards give up their posts and stop watching the walls for invaders?

As Serigala and his angry horde of followers begin to gather at the bottom of the castle hill, time is running out to rescue Captain Nibbles. After being kidnapped by Serigala's giant bees, new heroes must arise to help the hamsters rescue their captain from captivity in the nest of the bees and return him to the castle to face the attack of the black hearts.

To make matters worse, Barnaby Bunch lies at the bottom of a dark pit trap. The hamsters, with the help of Sky Commander Paffuto, must find the Life Stone, which is hidden in the den of the cinnamon bears, then find the black echo hole where Barnaby's life has come to an end. The castle has never been weaker, and Serigala and his army have never been stronger.

Will Serigala retake the castle? Will the hamsters and all the forest animals come under his rule once again? Will the light of the castle be extinguished? How will goodness and hope ever prevail again? Who will arise to defend the castle?
