Exposition and Conflict : Once upon a time, there was a famine going on. There was a tortoise who was very cunning but was starving for days. Then he heard that, the Sky Gods are arranging a feast for birds and will be held in the Sky God's castle.
Rising Action : The tortoise created a plan to join the birds on their feast but he needed feathers to fly up to the castle. So he went to the birds and asked them to take him with them. They were kind, so they each gave him their feathers so he could go with them.
Rising Action : As he was smart, he created a plan to trick the birds. He told the birds that, there is a tradition of new names when there is a feast of the Sky Gods. The birds believed him as he seemed wise to them. They each took a new name. Then he told everyone that his new name will be "All of you".
Climax : When the food was served. The tortoise ordered everyone to stop. When they asked why, he simply went to the Gods and asked them who all these food was for, they replied, "This is for all of you". Then he faced the birds and told them, "You heard them, this is all for me." Then he ate all the food without leaving anything for them.
Falling Action : The birds were so angry at his trickery and behavior that they took each of the feathers the gave to him and threw him off the castle. As he didn't have feathers, he couldn't fly. So, he fell to the ground on his back. That's when his shell cracked. That is why, Tortoise's shell is not smooth.
Conclusion : After his shell broke, he was crying for days and weeks. Then the birds took pity on him and fixed his shell. That's why, it's shell doesn't look plain. That day, the tortoise learned his lesson and swore never to trick anyone for his own benefits.
