Captain Green and the Eco-Teens

Captain Green and the Eco-Teens was a non-violent cartoon seen in the episode "The "Good Old Days!""

Background
When Timmy Turner's grandfather, Pappy, was babysitting him one day, he noticed that Pappy did not seem to like any of the things that younger people liked. After trying to show Pappy some of his cool things to no avail, Timmy gave up and went off to watch this cartoon. Pappy was also interested in cartoons, and watched alongside Timmy. Pappy was disgusted by the non-violent cartoon, and reminisced of the cartoons of his day which were more violent and not afraid to take risks. Timmy protested that the cartoons of his day weren't that bad, when Captain Green appeared on television and started doing a lame "rainforest rap", causing Timmy to acknowledge his grandfather being right, and he turned off the television.
