You don't think the treehouse is really haunted, do you?

After Lauren's brother's toy Donkey is thrown up there by the mean boys from school, it's up to Lauren and Twilight to get him back and to solve the spooky mystery. Little do they know, they're not the only ones in for a Starlight Surprise . . .
