Something

Something is a very young ghost who Casper encountered at least twice or so. He was first seen lost in the Enchanted Forest, taken to the haunted house Casper and the Ghostly Trio live, and causing a lot of mischief to the Ghostly Trio. He was seen again at the same forest while Casper was heading to Wendy​​​'s house, and carelessly played with Wendy's wand, accidentally turned her to stone. When the wand he used was burned in the fireplace, he had to go with Casper to get a new wand for her, and boy was that a long journey just to do that. All of this happened before Casper became the Professor of Friendship, and the Friendship School was founded.
