It was already math again when he got used to standing up right on his toes. It was during a test when he changed twice at the same time.
Soon Timmy's feet started to cramp up again in his white sneakers. He knew he couldn't take them off but he thought they wouldn't break but all of a sudden there was a huge rip.
HIs feet were full dog's feet but without the fur. The claws were done and the pads had even fully formed. HIs feet were so elongated but they were about 5 inches out of his shoes. He couldn't take off the remains of his shoes so he took his p.e shoes and put them on over his showing parts of the dog's feet. He had to walk on his tippy toes but no one saw the huge change.
Then he got to p.e the next day still wearing his p.e shoes over his dog feet. On that day his class was supposed to run the mile but because of his misshapen legs he couldn't run on his toes so he decided to run on all fours.
He finished the run in under 5 minutes and in front of everyone else. He went to take a drink when he started feeling warm. He check what was wrong when he saw fur growing on his legs. The fur completely took over his legs and feet and his tail so he was compleately a dog from the waist down except for the huge bump of a tail.
He just yelled, "HOLY CRAP." so loud everyone stopped running and stared and he just stared at them back like there was nothing wrong.
It was just a few more changes until he was fully changed.
