[2] The story follows Casper as he join forces with Wendy the Good Little Witch and Hot Stuff the Little Devil to stop a monstrous threat.

[3] In the town of New York City, Casper and his cousin Spooky are getting lessons from their uncles the Ghostly Trio: Fusso, Lazo, and Fatso as they demonstrate by scaring a local family on the subway.

Casper doesn't understand why, so in a school of Spookytown, the Trio inform him that they must keep the scares in Ghostburg intact in order to keep the monstrous Volbragg contained.

Hot Stuff decides to save them by pretending to be a mud monster and demands the ogres to let them go and entraps them with the net.

Casper, Wendy, and Hot Stuff reunite and witness the chaos as the many ghosts and ghouls were running from the monstrous beast.

Later, everyone in Spookytown mourns for Hot Stuff's apparent death, but it is revealed by his parents that the only way to bring him back to life is by dumping him in the fire.
