Gloop

Gloop is a location in the PJ Masks television series. It is the world where Gloop the Third and his Gloopets come from. It was first seen in the Season 6 episode "Heroes of Space."
The exact nature of Gloop is currently unknown; it could be a different dimension like Mystery Mountain, or another planet somewhere beyond the solar system in outer space. The latter seems most likely since other planets can be seen in the sky from Gloop's surface.
Regardless of its location, radio contact between Earth and this world is still possible with the PJ Communicators.
Gloop the Third and the Gloopets can travel between here and Earth through a black hole.
Gloop appears to be mostly a barren wasteland filled with mushrooms and other exotic plants. Many puddles of gloop can be found on the surface since Gloop and his Gloopets use it for their various plots. There are even volcanoes surrounding the area.
There is also a docking and refueling station for Gloop the Third’s Gloopster, a telescope and a defense system too. 
Lots of space junk like satellites can be seen near the black hole.
It is unknown if Gloop the Third and the Gloopets are the only inhabitants of Gloop.
== Trivia ==
* This is the third location to lead to a different dimension.
** The first location is Mystery Mountain.
** The second location is Zoomzania.
** The third location is Ice World.
* Seeing it is classified as a planet in space like Zoomzania, Gloop apparently has gravity and an atmosphere with oxygen similar to Earth, hence why An Yu, Ice Cub and Bastet are able to breathe and walk around there despite not having spacesuits.
* It is unknown how the black hole wasn't seen in space in the other episodes.
** Out-of-universe, it is because Gloop and Gloop the Third and the Gloopets were not created yet.
* The French name for Gloop is Galaxea.
* The Gloop splat looks different on Gloop. It is probably because Gloop the Third said he would make a new kind in his debut episode, as Newton Star was able to use his star power to break it.
