As I walk walking through the forest, a bear attacked me. In retaliation, I got my bag out and threw it at the bear. The bag hit the bear in the face, and a tree fell on the bear. The bear got angry, bit the tree, and I used the hidden powers of my spine to whip the bear in the face, which caused the ground around the bear to vibrate and throw it off balance. I ran home, got a lawnmower and mowed the fur off the bear, and it became a tuna.
