"Catboy and Master Fang's Sword" is the second half of the 6th episode in Season 1 of PJ Masks.
Connor has a poster of Master Fang above his headboard. He explains that his hero is the greatest kung fu master. Greg and Amaya arrive, and want to watch Master Fang on TV. They remind him that Master Fang never gets angry, but Master Fang announces that his sword was stolen last night. By night, they transform (although the poster is replaced with a shot of Catboy's poster of a Yellow-Clad-Cat-Man), and find Night Ninja with Master Fang's sword. Catboy keeps getting angry so they can get Master Fang's sword back from Night Ninja. But no matter how many times Gekko and Owlette try to tell Catboy to stop getting angry, he just wouldn't listen.
