After the Harvey's go on vacation, Casper's friends throw him a party to cheer him up but Carrigan turns them into ghosts and hides them somewhere in the manor as revenge for being tricked into crossing over. You must use various items to travel around Whipstaff to find traces of Casper's friends and take pictures of them for hints plus the end of the game, and collect items.
Cancelled Sequel[]
There was supposed to be a sequel as stated in the ending and the manual where you would help Casper bring his friends back to life but Morning Star went bankrupt before it was made.
