Two Brilliant Inventors (Japanese: がんばれリトルチュー)

Little Chu misunderstands when his grandfather calls his new solar-powered sunglasses "useless". Dr. Chu was actually talking about wearing them inside. But Chewy thinks his invention doesn't measure up and vows to make it better. And now, thanks to Pecola and another little misunderstanding, Miss Lucky is reporting on live TV that there is an invention competition going on between Dr. Chu and Little Chu. The whole town is curious about the sudden rivalry. Well, Little Chu's new souped-up sunglasses are so powerful they take him flying into the sky. Thank goodness for Dr. Chu and the Mad Mouse for a daring rescue, with a little help from Pecola, of course.
