The PJ Masks travel to another world with their shapeshifting pets to their homeland, Shape-topia.
The episode begins in Amaya's house where Greg is helping Amaya and her parents clean up the attic while Snowdrop was busy reading some old books and Glider was playing with Amaya's old baby toys. When suddenly, Connor and Lucky, who have returned from the library, went through the entrance to check things out as Snowdrop and Glider noticed the old book under Connor's arm.
Snowdrop flies over to it and grabs the book out of Connor's arm as she opens it and soon realizes what it was. Confused, the three kids go over to their pets to ask them what was special about the book as Lucky explains that it's a spellbook from their homeland, Shape-topia. Glider explains that Shape-topia is a place where he, Snowdrop, and Lucky are from and where they are taught to use their magic before they are sent to Earth to find some humans to live with. Later in Amaya's room, the kids and their pets examined the book just when Greg opened it, they find an old piece of paper that is actually a map of Shape-topia.
As he picks it up, the map and the pages of the book suddenly begin to glow below them. Then suddenly, a portal begins to open and soon it starts sucking Connor, Greg, Amaya, and their pets into it's vortex. They find themselves transported down the portal and after transforming into new outfits that resembles their pets, Connor, Greg, and Amaya, along with their pets, land on the outskirts of Shape-topia and they look round in wonder. As they were done looking around, Connor looks down at Lucky and asks him how he, Greg, and Amaya got here. Lucky realized that the map from the book had magically whisked them away along with their pets.
Amaya asks if there was a way she and the boys can get back home to the real world, but Lucky didn't know. Luckily, Snowdrop tells them that her father, Wisewing, knows how he can get them home. The pets then lead their owners to the city, Shape-topia.
The group arrive at Town Square where millions of shape-shifting animal citizens were staring at their friends' human owners with looks of awe while others were looking at them with curiosity. The kids seemed uncomfortable about the animals around them, but Lucky assures them that everyone around the city is friendly. Well, almost all of them when a cobra slithers towards them!
Shocked, Greg jumped as Glider confronts the cobra and tells him to get out of their way. The cobra laughed as he swat his tail onto Glider who flew above him and cast a glare at the cobra before landing on the ground to introduce him to the kids. The cobra, who was name Viper, flicked his tongue in greeting.
Although scared, Amaya greeted back as Greg calmed down Glider and before the cobra could ask more questions, the three kids followed their pets to Snowdrop's home avenue at an icy place called Icy Avenue. There, they went to an ice palace where they are greeted by other snowy owls and they were all very friendly, including one that lead them to the library where they met Snowdrop's father, Wisewing.
