Because I couldn't unplug the toilet with a plunger, I had to dismantle the entire fixture, no small feat for a non-plumber. Jammed inside the drain was a purple rubber dinosaur, which belonged to my five-year-old son. I painstakingly got all the toilet parts together again, the tank filled, and I flushed it.
However, it didn't work much better than before! As I pondered what to do next, my son walked into the bathroom. I pointed to the purple dinosaur I had just dislodged and told him that the toilet still wasn't working. "Did you get the green one, too?" he asked.
