Tropes used in SuperTuxKart include:

• Bonnie Scotland: The "Scotland" track.
• Build Like an Egyptian: The "Shifting Sands" track.
• Car Fu
• The Computer Is a Cheating Bastard: In the race against Nolok in the story mode, Nolok gets to set bubblegum (which for him looks like some sort of green slime with spikes) and activate a flyswatter (which for him looks like a hammer) at will. Given Nolok's Artificial Stupidity, however, it doesn't help him all that much.

• Jungle Japes: The "Amazonian Journey" track. Mild example with the "Secret Garden" track.
