Clank Challenges were challenges that were completed with Clank on Metalis or Dayni Moon, fighting for Robot War III. Each of the Clank Challenges fell into one of the three categories. In Destruction Derby, Clank was inside a fighting torso (e.g. saw or electric torso) and had to defeat similar torsos in a free-for-all match. In Gadgebot Toss, Clank was in a tossing torso and had to pick up a gadgebot and toss it into a goal. The robot that reached the goal limit first won the match. In Gadgebot Survival, Clank controlled a group of gadgebots in a 2D level. The gadgebots had to get past certain obstacles and get into the goal.
