This item has three styles, named "Normal", "Demoman", and "Pyro". The "Demoman" style gives Tux an eyepatch and the "Pyro" style gives Tux Pyro's gas mask and turns the flippers grey to resemble Pyro's boots.
This item was awarded to players who launched Team Fortress 2 using any Linux distribution between February 14th, 2013 and March 1st, 2013. The Tux was still obtainable in-game past the original stated date. It was not until mid to late-March that the Tux finally became unobtainable.
Although Valve initially said the Tux would become tradable once the promotion was over, it has not been done and it is unknown whether it will eventually happen or not.
