The player must use various items to travel around Whipstaff to find traces of Casper's friends and take pictures of them for hints and collect items while defending against attacks by the Ghostly Trio who are on Carrigan's side. There was supposed to be a sequel as stated in the ending and the manual where the player would help Casper turn his friends back into "fleshies" but Morning Star went bankrupt before it was made. Made by Microïds and Planet Interactive in 2002 it is one of few video games in which Casper can actually go through walls though only through the ones within each level. The Ghostly Trio have turned all the adults in town (presumably Friendship, Maine) into zombies leaving the children scared at the mercy of the Trio. The old Schoolmistress of the manor has them call in Dr. James Harvey to stop them only to become a zombie himself capable only of walking in front of him. It's up to Casper to help safely guide him through each of five levels using various transformations and objects to help the zombie Doctor collect flasks with the formula to cure him. There also six children in each level to rescue though the player does not need to in order to finish a level. However, Casper needs to save every child to become Hero of the Day. The Ghostly Trio show up in each level occasionally to scare Dr. Harvey and throw him off course and Casper must deflect their attacks. Silicon Graphics workstations using Alias software were used to generate the character graphics and backgrounds in the Saturn/PlayStation/3DO game. Reviewing the 3DO version, "Electronic Gaming Monthly"s team of four reviewers criticized that load times are frequent, it is easy to get lost, and that the puzzles are often obscure or even don't make sense. They nonetheless had a generally positive response to the game, with Sushi-X deeming it a strong last hurrah for the 3DO. They cited the stunning graphics and wide variety of gameplay elements. A critic for "Next Generation" agreed that the graphics are exceptional, noting in particular the ghosts which have true transparency. While also agreeing that some of the puzzles don't make sense, he felt the game was generally easy enough for its young target audience, and concluded it to be a solid though not amazing game. The magazine's brief reviews of the PlayStation and Saturn versions made similar comments. "Sega Saturn Magazine" gave the Saturn version a 70%, calling it "a decent enough effort with what is a particularly sugary film, spoilt by some frustrating flaws in the gameplay and action that is too repetitive."
