Johnny Test - Season 2

Average suburban boy Johnny Test is always ready for action, even when it means becoming the test subject for his genius twin sisters, Susan and Mary. Their outrageous scientific experiments turn everyday life into wild adventures, with Johnny often dragged into fighting evil villains along the way. Brave, gung-ho and rarely alone, he takes on whatever his sisters dream up as long as his genetically engineered super dog, Dukey, comes along.
