09-LAND, SEA, OR SKY？

LAND, SEA, OR SKY? At MIDNIGHT, Thea, Trap, Benjamin, and I went to the river. How would the professor get there? By land, by SEA, or by sky? You see, the professor liked to use many different types of transportation trucks, helicopters, submarines. They were all made in his laboratory. Every one ran on solar energy. He was always perfecting them. One day, the professor wanted to pass on his inventions to the world. A planet without any pollution was his BIGGEST DREAM. I paced up and down the riverbank. Benjamin stuck to my side like glue. "Tell me

again, Uncle, about the time you saw the professor on Mouse Everest. That must have been so cool," he squeaked. "I wonder if I could be the professor's assistant while we're here. Can you ask him, Uncle? Can you? Can you?" I nodded. The professor had never met Benjamin, but I knew he would love him. Who wouldn't love such a sweet, adorable mouse? Suddenly, the water began foaming with waves. A yellow submarine decorated with cheese holes broke the surface. With a loud POP! the hatch opened. A pair of mouse ears stuck out. "Professor von Volt!" I called. "Stilton, Geronime Stilien!" the professor answered. "Welcome, my friend!"
