Sonic Johnny is the second part of 9th episode and the 18th episode over all.
Johnny's parents got the Johnny the Lame-o Slow-mo Scooter because it is the safest one (and the cheapest). Susan and Mary offer to give Johnny their Sonic Super Scooter. They told him not to touch the red button, knowing he couldn't resist doing so. Johnny could not resist to pressing the mach 9 button. A police officer tried to stop them because it was too dangerous. When he and Dukey try to jump over several buses, they are sent to a damaged future ten years later because they were going so fast, everything in Porkbelly was destroyed. The same police officer saw them and wanted to get them because they were the ones who caused Porkbelly to become destroyed. Johnny pressed the button again hoping to go back home, but he and Dukey went further in the future, causing more damage. They come to a cleaner Porkbelly, but they are still wanted. Again that policeman found them and tried to get them. Once again Johnny and Dukey press the button and go even further. Robo-cops find them. Johnny and Dukey go to the retirement home Susan and Mary were staying at, dressed up as Gil. They ask the elderly Susan and Mary how to get back. They both said it was a joke, and that they knew he would press the button, but didn't know all that damage would happen. Susan and Mary take them back to the lab, and built them a modified scooter to take them home. When Johnny and Dukey return home, they are back when Johnny was begging his parents for a new scooter. Again, Susan and Mary asked him if he wanted a Sonic Super Scooter. Johnny quickly said "no" making Susan and Mary confused.
