Porgs were a sea bird species native to the planet Ahch-To, where Jedi Master Luke Skywalker made his exile in the years following the victory over the Galactic Empire. The creatures, who dwelled on the cliffs of the island where Skywalker lived, could build nests and fly. The first appearance of the creatures was in Star Wars: The Last Jedi.
This creature was later joining Millennium Falcon after Chewbacca left Ahch-To.
And today, we found a tutorial on how to build this cute creature from Iian Heath flickr page! Have fun!
