Tom is forced to drag his little sister around the funfair, going on all the rides she wants and playing whatever games she chooses. Then his friends see him- so embarrassing!

Tom grumbles on, even when his sister wins a goldfish. She is delighted! They take it home and give it a new home in a glass bowl. Tom is still sore at having to look after her and begins banging the goldfish bowl. When the fish floats to the top, he quickly exits, leaving his sister to discover her poor pet.

Then Tom starts to see the goldfish everywhere, in glasses of water and the school swimming pool.

This scaled spectre wants revenge! Will the fish stop haunting Tom? Or will Tom be faced with the ghostly fish forever?
