How does L.J. Jones steal Kenny's dinosaurs? Why doesn't Kenny go get them back?
L.J. Jones wants to have the "World's Greatest Dinosaur War Ever" with Kenny. Kenny gets all of his toy dinosaurs. While they are playing, L.J. says that some of them have radioactive poisoning and need to be buried before they infect the others. Kenny forgets about the buried dinosaurs until later. When he goes out to dig them up, he finds that all of them are gone.
Kenny doesn't go get them back because he is embarrassed that L.J. tricked him. He felt so dumb for not being able to see the trick coming.
