PJ Masks - Season 1 Episode 48 Gekko and the Rock of All Power

Greg wondered if he could win at least one medal to declare him being strong. By the time they went out of the library, they saw lamposts being bent. By night, they saw Night Ninja chasing a rock called the Rock of All Power. Amaya heard about the rock in her Kung Fu book that whoever breaks the rock will be awarded with a medal. Gekko was so tempted to break the rock to get the medal since he has the power of strength instead of protecting his friends and their HQ. But while he tries to stop the rock, he breaks it, not meaning to. He says that he felt stronger than ever, and that true strength comes from caring for your friends. That is the best strength.
