The Land Before Crime is a fan story written by ArthurEngine. It's a story that takes place 8 years after the main Robotboy timeline.
After hearing Perry's lame idea of writing a story about dinosaurs, Queen Grace decides to break out of prison and use some special technology to bring dinosaurs back to life for her perfect wedding with Perry, and kidnapping Krystal in the process.
- The title is a pun on the Universal Studios animated movie and its direct-to-video sequels, The Land Before Time.
- The way the Giganotosaurus dies is similar to The Land Before Time V.
