Still pursued by the evil Count Olaf, the Baudelaire orphans attempt to reach a very important VFD meeting, but first they must travel in a rattletrap submarine to the Gorgonian Grotto, a dangerous underwater cave, in search of the sugar bowl.

On the run after being falsely accused of murder, the three Baudelaire orphans find themselves in the Heimlich Hospital, with the evil Count Olaf in close pursuit.

The story may seem cheery at first, when the Baudelaire children spend time in the company of some interesting reptiles and a giddy uncle, but don't be fooled. If you know anything at all about the unlucky Baudelaire children, you already know that even pleasant events lead down the same road to misery....
