The Life-Size Dinosaur is a scam idea that the Eds came up with in "An Ed Too Many." After escaping from Sarah, who had developed a crush on Edd at the time, they set up shop in Edd's garage so they could create this scam. However, soon after starting work on it, Sarah found her way into the garage and managed to wreck the scam along with all the progress the Eds had made on it. She also managed to cover Edd in the quick-drying papier-mâché that they were planning to use to make the dinosaur, ensuring that Edd couldn't move and they couldn't make the scam.
