She wishes her life could be more like the stories in those! Squiglet is sure he can help, and takes her off to a fancy dress shop where she picks out her very own superhero costume! Now all she needs is a superhero vehicle and Squiglet obliges, squiggling her a special superhero tractor - the cow mobile! But now that Cordelia is a fully fledged superhero, she wonders what to do next. What do superheroes do exactly? They help people! So Cordelia just needs someone to help. Her best friend is the farmer - so they head back to the farm to see if they can help him. When they arrive, they discover that the grass has grown very tall without Cordelia chewing it! and the farmer's trapped inside it all! A look at the Squiggle Pad gives them the answer a lawnmower! As soon as Squiglet has squiggled one, Cordelia gets to work .. and rescues the farmer in no time. And when he sees Cordelia's tractor, he's thrilled.
