Once upon a time, there was a boy named Tai Thumb. He was a Thumbling. His life was not the best, in fact, right now he might even starve to death. Despite that, he took joy in the little things in life and even hung out with his friends quite a bit. However, word had gone out—the king of the Thumbling Kingdom will step down from the throne. A four-year competition. Two years to prepare. All young Thumblings, 14-18 years old, must compete.
