Young Gillbert is the prince of the underwater world of Atlanticus.
Together with his best friend Sherbert and mysterious new friend Anne
Phibian, Gillbert is curious to where all these bottled messages
floating throughout the ocean are coming from. Could the fiery
Pyrockians from space have something to do with it? Or maybe it is
something more mysteriously monstrous? Plus, Gillbert must deal with
being a new big brother, when his little sister Matilda is actually
much, much bigger than him! The most fun had under the sea since "The
Little Merman"! Created by Tiny Titan's Art Baltazar!
