Time spent by the sea can be refreshing and rejuvenating, and may be just the thing the Baudelaire orphans need after their exhausting mountain adventure.
Violet, who likes to invent things, would surely find interesting contraptions to explore in a sea-bound vessel such as a submarine. Klaus, an avid reader, would certainly be interested in doing some research into the peculiar habits of certain mushrooms. And Sunny, who loves to bite things and is learning to cook, may enjoy the surprising food that comes from the sea.
Regardless of all the wonders the world of water has to offer, the Baudelaire siblings should hone their skills while ocean bound, just in case this journey turns out to be the most dreadful yet in a series of unfortunate events.
