Wisss is the son of King Ploobis and Queen Peuta.

A one-note character defined by his addiction to smoking craters (becoming a "crater head"), Wisss appeared sporadically in the "Land of Gorch" sketches on Saturday Night Live. He was only used four times in the entire run, something that was acknowledged by Scred in one of their last appearances when he exclaimed: "Wisss! We haven't seen you since November!" This was only the third time Wisss had been seen, and he would appear one last time in season two with Lily Tomlin.

Wisss can also be spotted in The Muppet Movie's Rainbow Connection finale.
