The second grade spelling bee is here, and Rex is absolutely terrified. She is a terrible speller and is worried she will embarrass herself in front of the entire class. Her best friend Pinky, on the other hand, is feeling very confident. He is a great speller and expects to easily win the championship title once again. But Pinky is not prepared for the new kid in class, who turns out to be a surprisingly tough competitor. Even worse, Pinky is definitely not prepared to have a completely unexpected and highly embarrassing accident right in the middle of the competition. Suddenly, winning or losing the spelling bee does not matter at all. Fortunately, Pinky can count on Rex to step up and make him feel better on what turns out to be the worst day ever.
