Ages 5 years & over. Boris the skull persuades the witch Griselda that she needs a holiday. Before she departs for her cousin Veronicas home Morgan Castle in Pembrokeshire she castes a spell to change the boys holiday plans, but to her distress discovers on arrival that her cousin will not allow children of holiday makers to be eaten whilst they are staying in the castle (bad for custom the parents get upset and will not come back next year). So Griselda magicks the boys to the Kingdom of the Deep and follows to eat them there. In the Kingdom of the Deep the boys are taken by a little mermaid to meet her mother a mermaid queen who in her foolish desire to dance has allowed the Princess of the Night to steal her tail and take possession of her kingdom. With the help of Snuggle the boys get back the tail and in her delight the mermaid Queen begins to sing, breaking the spell of the Princess of the Night.
