While Lion-O practices with the Sword of Omens. Mumm-Ra forces Jaga to reveal the location of the Tower of Omens; which has the Book of Omens hidden within. In the Jungle, Snarf, while trying to fill his appetite causes a ruckus which reveals the entrance to a temple leading to the Tower. After entering the temple, the Cats each solve a series of deadly puzzles and reach the Tower's entrance. Lion-O uses the Eye of Thundera and finds a button that opens the way to the Tower of Omens, which Tygra opens with his whip. Mumm-Ra then reaches the Tower, having located it thanks to Jaga. A fierce battle takes place in the tower where Jaga sacrifices himself to save Lion-O and the others. Soon afterwards, the Cats claim the Book of Omens, where Lion-O discovers it is actually blank.
