Tux

Tux is one of the main characters in SuperTuxKart.

About
Tux is a penguin character and the official mascot of the Linux kernel. Originally created as an entry to a Linux logo competition, Tux is the most commonly used icon for Linux, although different Linux distributions depict Tux in various styles. The character is used in many other Linux programs and as a general symbol of Linux.

In SuperTuxKart, he has a female counterpart named "Penny" (sometimes called "Gown") who is purple and white (SuperTuxKart had Penny/Gown as a main character before 0.6 and had a map called "Gown's Bow" from 0.0 to 0.4, which was reworked into Star Track in 0.5).
