Sister spirit : Given a very bad, very short haircut by her jealous older sister, Hannah, nine-year-old Cassie seeks revenge by making it seem as if Hannah's closet is haunted. Sleep-over : It's Olivia's very first sleepover. She's super-excited and worried. A hundred different things could go wrong, all of them totally embarrassing! Olivia doesn't want to let her best friend down. BUT -- maybe she should just stay home? Dancing queen : Charlie is buzzing! She's just had her first ever modern dance class! It's so much better than stuffy old ballet. Even though the trendy girls totally tease her. And now there's the performance to worry about. But none of that seems to matter once the music plays and Charlie starts to dance.
