Here are two turtles, Franklin and Cruiser living a mediocre life. They never left the house because everyone tantalized and jeered them for looking different than the rest. They were seen as aliens.
Their only friend Lola the peacock, came to visit erratically. She tried to feint them out of the house. She also tried to fortify them and help them face the people outside. She tersely explained her plan.
Franklin and Cruiser finally adjourned from their house and showed unflinching bravery. They took their wings and flew off to Narnia where they would be accepted and could live in harmony.
