Esther was cool. She was so smart that she gained the ability to shapeshift. Her favourite animals were cows, so she often changed into that.
When David kicked her out of the palace, she was very distressed and decided to seek revenge on him.
They became arch enemies.
One day, when David was being his usual smug, silly self, Esther formed a plan.
She and her millions of cow followers (because she was the Queen of them) were going to take revenge on David and his cruelty.
Meanwhile, David was sitting doing nothing and generally becoming fat. AND SUDDENLY, THERE WAS A MASSIVE CRASH AT THE DOORS OF HIS PALACE. THE COWS HAD COME!
Esther laughed evilly and burst into the palace. "I TOLD YOU YOU'D BE SORRY!" she yelled and transformed into a mighty cow.
David screamed very high-pitched like a girl and began to cry because he was very scared.
