Short story alert:

Once upon a time there was a baby Japanese spider crab that was born way deep down in the Pacific Ocean. After he was hatched, he began his journey into adulthood. It took him four stages to develop into adulthood. He was so happy when he reached the fourth stage. He was now an adult Japanese spider crab. He was amazed at how long his ten legs were and that the two front legs had claws on them. He would spend his days at the bottom of the Pacific Ocean off the coast of Japan searching for food to eat. His favorites were algae and small fish. He also loved to decorate his exoskeleton using sponges and kelp. He thought he looked beautiful and the decorations helped him hide from the predators that liked to try and eat him. He lost one of his claws trying to get away from the octopus that tried to eat him one night for dinner. He was a lucky Japanese spider crab because his claw grew back when he went through the molten process. Oh, how he loved to scavenge the bottom of the ocean for food! THE END.
