About The Show
Johnny Test is a fearless 11-year-old boy who likes to causes problems in the family and often in the city. He lives with his super dog Dukey and his 13-year-old twin sisters, Susan and Mary. His sisters are genius scientists who use Johhny as a guinea pig for all of their crazy scientific experiments. With their help, Johnny gets supernatural powers and can even travel through time. Sometimes, the experiments have strange side effects like hairstyles that change every second! Even though Johnny is often causing trouble and messing with his sisters’ inventions, he always learns from his mistakes.
