Plot
As a result of Casper being too friendly with a boy named Jimmy Bradley and failing to scare enough humans, Kibosh, the King of the Underworld, has Casper enrolled into a Scare School, to prevent him from being banished into the Valley of the Shadows, headed by the two-headed headmaster Alder and Dash. At Scare School he befriends Ra, a mummy with unraveling issues and Mantha, a zombie girl who keeps falling apart, as well as Cappy, a pirate who takes them to the school, and his parrot Beaky.

There they learn to keep the Balance between scaring "fleshies" too often or too little both of which, the staff believe, would cause them to rise up and dominate the creatures of the Underworld. His first three lessons result in Casper being given detention from the teachers. The school bully, a vampire, named Thatch and his cronies spy on Casper in an attempt to sabotage him.

Casper feels unable to cope with having to be scary so he decides to go to the Valley of the Shadows by himself believing the Balance would have to go without him. Upon his arrival Casper finds the Valley to be a colorful garden and he meets his great-aunt Spitzy, who the Ghostly Trio claimed were not allowed to talk about, and the other creatures who were banished there for refusing to scare humans.

Meanwhile, Alder and Dash plot to use a petrification potion to turn Kibosh into stone and take over the Underworld and Deedstown. They test the potion on the Ghostly Trio, who arrive to meet the headmaster(s) after Casper's disappearance, before inviting Kibosh. When Casper's friends discover this they go to the Valley of the Shadows to warn him. Upon their arrival they discover that they can leave the Valley although the residents believe they cannot and had never even tried to. Casper then goes to Deedstown with his friends to stop Alder and Dash in their plot.

The headmasters are convinced to stop by their "ancle" (aunt and uncle in one) Belle and Murray, from the Valley of the Shadows, and when everyone is returned to their original forms Kibosh allows the creatures to be friends with "fleshies" every once in a while. Kibosh confides in Casper that he once had two human friends and shows him a photograph. He tells him that being scary and growing up is hard, but he has confidence in Casper. Meanwhile, Cappy and Beaky soar over the soccer field while Thatch swabs the deck as punishment for his actions.
