Back on Third Earth, Mumm-Ra is just about to boil the book when Lion-O calls for the sword, and it brings him and Snarf back outside. Mumm-Ra takes the sword and looks through it at the book, and he gets sucked in. But Lion-O has to save him because of the code of Thundera, and Lion-O does save him. Panthro and Tygra arrive with the key, and they realize it is the one the book was asking for.
