Tricycle of Terror is the second segment from the fourteenth episode of The Grim Adventures of Billy & Mandy.


When Billy crashes his bicycle, he obtains a free tricycle from a mysterious boy in a supernatural porta-potty. While Billy loves his tricycle, which he calls Trykie, he is also mocked because of it by Irwin, Pud'n and Sperg. Because of this Trykie moves on his own, and attacks the three of them. Later, Mandy realizes the problem with Trykie, and Grim confirms that he is cursed. Finally, Billy realizes that Trykie is evil, and he lets Mandy destroy him once and for all.

  • This episode is a spoof of Stephen King's Christine.
  • While Billy is walking home after his first bike gets completely destroyed, he actually outruns a very small turtle that is only visible for a very short while.
  • In one part of the episode, Sperg throws Trykie over the side of a cliff. This cliff is actually based on the cover of the poem book "Where the Sidewalk Ends" by Shel Silverstein right down to the dog stuck in the hole and the sign that reads "EDGE". This is also supported by Sperg saying "This is where the sidewalk ends, baby!"
  • This is the last episode to air during Cartoon Network's Powerhouse era.
  • When Mandy is crushing Trykie with the garage door, the flower on her dress has blue petals instead of yellow, similar to the pilot.
  • For some fans, Irwin and Pud'n no doubt brought being maimed by the tricycle onto themselves. While Trykie's actions are in no way excusable, the fact that they never apologized for cruelly mocking Billy about it and even seemed gleeful about it makes the fact that they were beaten to a pulp irrelevant. Sperg also deserved his punishment for his bullying ways.
