Jurassic Dork / Mascot Academy / Full Metal Johnny

S3 E17: "Jurassic Dork" Johnny mistakes the Museum of Natural History for a really big hobby shop, and comes home with a dinosaur egg that he thinks is an airplane model kit. (Johnny's dumb.) When it hatches, Johnny has a screeching, acid-spitting dinosaur on his hands. "Mascot Academy" In an effort to meet cheerleaders, Johnny matriculates at mascot college, where he mistakenly injures Kent Stevens, the college's arrogant star pupil. Months later, Johnny's enjoying his career as a professional mascot - playing a rotting fish head for a football team in Argentina - when Kent tracks him down to seek his revenge. "Full Metal Johnny" Thinking he's signing up for Fantasy Dodgeball Camp, Johnny accidentally joins the U.S. Army, and must endure bootcamp under the tutelage of the beautiful but tough-as-nails Sargeant Trixie. Or, rather, bootcamp must endure Johnny.
