Sssiii, a Slith of the male variety, was characterized by his red coloration and a weight of 60 kilograms. The Galactic Circus acquired him through unknown means, and he subsequently traveled with them to various worlds, notably Tatooine. Possessing an intellect akin to a 10-year-old Human, Sssiii lacked the ability to verbally communicate; instead, he used his tail to strike the ground as a means of communication. Sssiii's circus act involved entertaining audiences by engaging in games of chess with members of the audience.
Sssiii is featured as a non-player character within the roleplaying adventure titled Le facteur X, which was released in Casus Belli. Given that this French gaming magazine's article might not have undergone proper licensing, the canonicity of Sssiii remains uncertain.
