Assembly Guide
The ".S" (pronounced "dots") lineup consists of little upright panels which come with bases so they'll stand up; the panels have regularly-spaced holes in them. Along with the panels come 520 differently-coloured pegs that you can stick through the holes in the panels, to design your favourite nostalgic video-game characters! This is the Super Mario "A" set, which allows you to design Mario as well as other characters.
