Imagine having a lollipop that gives you the strength of a hundred men or a rocket-powered backpack that can send you to the Moon or genetically altering your dog to make him talk. Johnny Test can do all of that... and more! So it's not just another day in the life of a boy. Johnny Test chronicles the adventures of a fearless 11-year-old boy, his genetically engineered super dog Dukey and his 13-year-old super genius scientist twin sisters, Susan and Mary, who use Johnny as their guinea pig for their out-of-this-world scientific experiments. And half of the time their experiments cause something bad or earth-deadly to happen. Then they have to save the day after they started it.
