Pongwiffy is very, very bored. It is raining, and she has nothing to do. Pongwiffy is a witch of action who hates being cooped up. Her idea of a good day is to be out and about, swapping gossip and recipes and inviting herself to tea. But the incessant rain has put a stop to all that. Pongwiffy decides the witches need some sort of excitement. And what better than a holiday? It is the matter of a moment for Pongwiffy to take the coven's much treasured funds and blow them all on a trip to the ever popular holiday destination Sludgehaven-on-Sea. Which is precisely when the trouble starts.
