Hettie Hubble has once again caused chaos at Cackles and the East Wing is out of action. Now all the girls must share rooms until it can be repaired. Hettie is thrilled to be sharing with Cressie. Mona is not pleased to learn her new room mate is Belladonna. But sharing a room turns out not to be so much fun when Hettie discovers how loudly Cressie snores. After a sleepless night, Hettie finally snaps at her friend in Potions Class. Cressie tells her not to worry, her Mum always used a special lullaby to stop her snoring at home. That night Hettie takes out the spell and holds it under her candle. She is half way through when the paper catches light. Quickly she extinguishes the flame but the spell seems to have worked. Cressie is sleeping like a baby. But when Hettie wakes the following morning that's exactly what she finds!
