Arthur Season 3 Episode 3 Arthur Goes Crosswire / Sue Ellen and the Brainasaurous >Set at the same time as the previous episode, Sue Ellen and Brain choose to build a dinosaur model for their animal project. Sue Ellen wants to help, but Brain refuses to let her, paranoid that her model will be inaccurate. When Brain ends up doing the entire project by himself and neglects to use Sue Ellen's model, they argue and end up dropping Brain's model; Sue Ellen turns this into a dig site exhibit, which gets them a good grade. Meanwhile, Francine is paired with Buster, who avoids her so he does not have to work.
