Is it a beastie? Is it a kelpie? Is it a sea monster? Angus and his sister, Kirstie, have found something strange at the beach so they take it home to put it in the bath

who knows what it might be? At first they think it’s just a big old piece of seaweed, but in the morning it’s squeaking and splashing… the seaweed has hatched into a curious creature with little flippers

it’s the water horse!

The question is will Mum let Angus and Kirstie keep him

and what will they do with him if he just keeps on growing?
