The bus is suddenly hit by something from above. A sloppy brown substance oozes all over the bus as a mouthful of the burger almost crushes the tiny yellow vehicle. The class groaned in disgust and I felt inclined to do the same. "Fascinating, the process of eating, isn't it?" I took to the wheel and decided to submerge the bus briefly, to clean the burger from the windows. As we went under the soupy substance that was steadily filling Sabrina's stomach, the remains of the burger were washed away by the acids. I drove us back to the surface. Sabrina's stomach was becoming quite full. I wondered just how much she could pack down here.
