2. INTRODUCTION
Once upon a time, in a small village under the
sea, there was a school in the middle of the
ocean. There were so many different families
living there: The Lobster’s, The Crab’s, The
Whale’s, The Turtle’s, The Dolphin’s, The
Jellyfish’s and The Octopus’, living all together
in absolute peace.
Suddenly, a family of a hammerhead sharks
moved there and the peace was over.
