YMMV / The Backyardigans S 4 E 1 Robot Rampage

• Magnificent Bastard: Professor Bug is a self-proclaimed Evil Genius who seeks to take control of every last robot in Mega City. Stealthily infecting various robots with his "bugs" to distract local robot repairman Austin, Bug uses the opportunity to infect all Mega City robots with his bugs and bend them to his will. Cheerfully singing about his newfound power while still avoiding giving Austin any clues to his villainy, Bug—refusing to let even one robot possibly thwart him—focuses all his attention on tracking down uninfected robot Rosco, and sics the powerful Rex Robot onto Austin and his friends when he infiltrates Bug's lair. Even when beaten, Bug simply prompts to assist the heroes in repairing all the corrupting robots, noting that he now has plenty of free time on his hands since his scheme was foiled.
• Suspiciously Similar Song: The song "Screw Loose" bears more than a slight resemblance to the ABBA song "Chiquitita".
