Crocker is shown watching children's show and tells. When Timmy brings an actual dinosaur for show and tell, Crocker realizes that Timmy must have gotten it from fairies. Crocker then asks for a parent teacher conference, but Timmy quickly has his godparents pose as his parents. Crocker tries to expose them, but fails each time due to dumb luck. When he finds Chester and A.J. looking for the dinosaur, he promises they can enslave the Earth if he gets the dinosaur. However when he gets the dinosaur Timmy quickly uses a wish to replace the dinosaur with Mange. Crocker is then punished by Waxelplax due to him trapping her in a toilet paper cocoon. Crocker swears to Timmy that he will get Timmy's godparents and that they can't keep him here forever. He speaks too soon as Waxelplax then falls into one of Crocker's earlier failed traps, much to Timmy's delight.
On the last day of school, Crocker correctly suspects that Timmy has turned himself invisible using fairies, and using a Heat-Seeking Fairy Suit, tries to hunt down invisible Timmy and his fairies. Crocker's invention works and allows him to see Timmy, but Wanda beats him up and Timmy is wished back to normal before Crocker can grab him and prove he was invisible to the school.
Timmy wishes himself into the Internet and ends up in Crocker's computer. While spying on Crocker undergoing a humiliating dress-fitting ritual with his elderly mother, Timmy makes an audible noise in Crocker's computer, getting his attention. Crocker suspects Timmy is a computer virus and sends several after Timmy, and another to spy on Timmy's computer. Crocker's virus successfully collects video data of Cosmo and Wanda carelessly using magic, but Timmy intercepts and destroys the data before it can be uploaded using Crocker's other viruses. Timmy then uploads the Crocker dress fitting footage he captured earlier to the entire world, humiliating Crocker, who is also arrested when A.J. and the government trace the viruses back to him.
Although Crocker himself does not appear in this episode, Alden Bitteroot is the central villain and has all of Crocker's looks and mannerisms, with the exception that Bitteroot is obsessed with witches as opposed to fairies. In actuality, Bitteroot himself was a witch. It is unknown if Bitteroot is an ancestor of Crocker.

After mocking his students, Crocker dons summer garb and drives off on the ground in a jet-ski. At the end of the special, Crocker fails all the other students due to changes that Timmy's adventure had on the books that they had written about, while Timmy manages to get a rare A on his report, much to Crocker's dismay.
