Casper recognizes him and tells Mantha about the boy whose is Norman and that he is a bully who is always picking on Jimmy until Professor Burns interrupts him and makes him to go possess the fleshie. The former reanimates Norman and Casper tries to ask Norman for permission to posses him, Professor Burns tells him not to ask him and tells him to concentrate his energy and force his way in. Casper does as he is told and Norman does it too as he is "not gonna let some ghost push [him] around" and Norman ends up wrestling Casper and shoving him back into his body. Norman, still out of his body, hides behind it while Professor Burns dismisses the class and tries to put Norman back to sleep, unaware of what just happened. After everyone leaves, Norman rushes to Casper and possessses him, having almost complete control over him.

Meanwhile, Casper struggles to get control of his body and asks Norman if he doesn't want to go home. Norman then decides he wants to return to Deedstown so that he can bully kids with his stolen body. Casper then refuses to show him how to get back to Deedstown but when Norman threatens to mail "his girlfriends's" (Mantha's) head to China, Casper reluctantly agrees. Casper leads him to where the portal is and, after throwing the sleeping janitor outside, Norman returns to Deestown through the Dimension Tube.

Having heard of his "change", the Trio express their happiness, Stretch pats his head and tells him they knew Casper "had it in him", Fatso tells him of how he has never been so proud before and Stinky congratulates and hugs him. Norman then leaves, claiming that he has things to do and people to scare while the Trio hug each other and proudly watch him go.
