Tapio was worried. The house had got many new residents, since so many came from adventures. Toa of the Toa, Toa of Sound, Miira's Army, Matoran Hordika, Iruini... too many. Then suddenly, the door exploded. Some Rahkshi and Vahki stood there, ready to fight. They raised their tools and staffs. Tonga, in his lair, had decided that they had to be destroyed, Tapio and his friends. A fight ensued, the good guys won. After the battle, everybody discussed what just had happened. Toa of Sound knew what it was about. He told everybody that Tonga had unleashed an attack on them. They started a journey towards Tonga's Fortress.
