Matty Bratty Robots - Matty Bratty Adventure Chapter Book, #1

A Not-too Smart Boy Who Dares to Dream Big.  Part-inventor, part-dentist, robot builder, and scientist, nine-year-old MATTY BRATTY just might be a misunderstood genius. Matty Bratty Robots is the hilarious, clever tale of a boy who flunked third grade but is confident enough to think that he can be a scientist. After all, Albert Einstein is his pen pal, although Albert never writes back to Matty. When Matty builds some robots in his bedroom closet science lab, chaos happens. To quote Matty, "Great scientists cause accidents.
Smoke detectors were made by accident. My robots look like accidents, which proves that I am a great scientist." His stuffed dinosaur, DINO, can talk because Dino wears false teeth that Matty made from his baby teeth.
