The main characters in this book are a little witch and her black cat. The little witch tries to cast a spell to turn her black cat into a fish so it can have an easy bath before its birthday. However, her spell keeps going wrong, causing the black cat to change into something else again and again.

In this book, children will enjoy copying a series of imaginative and playful chants, such as “Blinch, Clinch, Flinch” and “Deesh, Reesh, Tremeesh,” while reinforcing digraph sounds.
