The user is a fourth-grade student, who, fortunately, missed the day of school when the class's substitute teacher was a witch named Ms. Grunkle.
After signing in at the schoolhouse, the user is transported to Haunted Island. With the aid of a large purple bat named Flap and a fortune teller named Madame Pomreeda, the user must rescue the thirteen lost classmates by collecting the students' "most prized possessions" from the island's educational activities. After these possessions, which reveal elements of the kid's personality, are collected, Madame Pomreeda transforms the classmate back with a poem that tells the monster to go away and the child to return.
