Pidge and the other members of The Voltron Force return to the Castle of Lions safely. They realize that Yurak will launch another attack come dawn. They also realize that only Voltron can defeat Haggar's Robeast. So The Voltron Force and Coran return to King Alfor's tomb to search for the missing Black Lion key. While there they see a group of Space Mice. Thinking the mice may know the location of the key to the Black Lion they trap the mice in a cage to question them. Upon discovering this Alura is appalled since the mice have been her friends since childhood. Alura talks to the mice and asks them about they key. They tell her they thought the key was pretty and took it to their nest as a good luck charm. They are released from the cage and return the key to The Voltron Force. With all five lions the Voltron Force heads into battle and defeats Haggar's Robeast handily.
