Behind the scenes Porgs were designed for the 2017 film Star Wars: Episode VIII The Last Jedi. They were conceived by writer/director Rian Johnson, who created them to digitally cover up the vast numbers of real-life puffins present on Skellig Michael, the filming site for Ahch-To.

The challenge fell to Star Wars creature concept designer Jake Lunt Davies. "The first iteration of porgs had seal fur and flippers instead of wings, then further down the line in the creative process, a decision was made to change this to feathers and make them more avian," Lunt Davies reveals.

Small, flat-muzzled avians that flock about the rocks and roost in the cliffs of Luke Skywalker's secluded island, porgs are inquisitive creatures.
