Kids like superheroes, so what could be better for tykes than becoming superheroes themselves? That's what happens at night for young friends Connor, Amaya and Greg. When they put on their pajamas and activate their animal amulets, they turn into their alter egos -- Catboy, Owlette and Gekko -- before embarking on adventures that are filled with action. Along the way, they solve mysteries and learn valuable lessons. The animated series is based on the Les Pyjamasques book series by French author Romuald Racioppo.

Octobella's vendetta against Gekko builds to unseen heights; Catboy and Owlette build a new vehicle of discovery and exploration, the PJ Sub.

Gekko tries to get Pirate Robot to be a chief instead of a pirate; Newton is desperate to study a rare asteroid, but Pirate Robot has seen it too and plans a hijack.

After ignoring the warnings, Pirate Robot gets himself and Newton captured; Newton creates a powerful Star Splat.

The PJ Masks seek to stop Night Ninja from stealing a magical ring hidden at the top of Mystery Mountain.
