When an ancient bottle is found washed up on the beach after a ferocious electrical storm all
the residents of Eerie-on-Sea seem to want it ... but should they in fact fear it? Legend has
it that the bottle contains an extraordinary secret that spells doom for the whole of
Eerie-on-Sea. Could it be true that the vast sea creature Gargantis has awoken from her
slumbers and is causing the large cracks that are appearing all across the town? Finding
themselves entrusted with the bottle Herbie and Violet discover they will need to ride the
terrible storm and pacify the creature if they want to save Eerie-on-Sea from sliding into the
ocean and being lost for ever.
