Once upon a time, in a deep blue ocean, lived a mermaid named Hillary. She had a beautiful sparkly tail and long flowing hair. Hillary loved exploring the ocean, but she had one big dream - to learn how to make a delicious cake like the humans do.

Hillary asked her friends, the dolphins and seahorses, if they knew how to make a cake. They giggled and said, 'Sorry, Hillary, but we don't know how to make cakes. We can help you find the ingredients though!'

So, Hillary and her friends went on an adventure to find the ingredients for the cake. They searched high and low, gathering things like flour, sugar, and eggs from sunken ships and hidden caves.

When they finally had all the ingredients, Hillary realized that she didn't know how to mix them together. She was feeling sad because she really wanted to eat the cake. Just then, an old wise turtle swam by. 'I can help you, young mermaid!' he said.

Hillary listened carefully to the turtle's instructions. She followed every step - mixing, pouring, and baking. Soon, a delicious aroma filled the ocean. Hillary's cake was ready!

Hillary shared the cake with all her friends, and they smiled and cheered as they took their first bites. They couldn't believe how yummy it was! Hillary was proud of herself for listening carefully and learning how to make the cake.
