Okay; It is not the Super Mario but its a Tux or Pingu which acts like Mario which makes it Mario Tux but its Super Tux. Super Tux is super cool game. Nice graphics, music and you get a Pingu to move it all the way through different difficulty 26 playable levels. And Oh! its available for MAC, Windows and Linux.
