Holly and Casper quickly become good friends, with Holly still believing that he is the snowman she built. Casper did not tell her he was a ghost because he did not want her to get scared and no longer want to be his friend, but the lie ate him up inside. Due to the fact that Casper couldn't scare, the ghostly trio brought spooky to impersonate Casper to scare people, but he was unable to scare and resorted to being mean, while pretending to be Casper he ran into Holly and insulted her and her family which caused her to be grumpy at Casper, resulting in tearing his Christmas card she was making in the real Casper's face. Holly is depressed by Casper's sudden aggression and holes herself up in her room, when her parents enter the room, they encourage her to give Casper another chance, which she does.
