Winnie's witchy bedtime

"It's midnight: bedtime for witches. Wilbur is soon snoring, but Winnie just can't get to sleep! She decides to try some sleepy spells to help her nod off, and soon there are frogs leaping around her bedroom and a rather pongy potion brewing. Nothing seems to work-until Winnie remembers her Big Book of Spells. Can she find the right spell before Wilbur wakes up for breakfast?"--Publisher.
