The Tourist Alien is a highly excitable alien being who stopped on Earth while he was on vacation.
After traveling throughout the Milky Way Galaxy, the alien stopped on Earth. He really wanted to go to Paris, London, New York, and Rome. He parked on the roof of the Firehouse and soon met Slimer. Slimer was astonished by his reckless behavior and decided to keep an eye on him. They walked up past a Plaza East construction site to the Central Park Zoo. The alien discovered he had no film loaded in his camera. A Delivery Robot took the alien aboard his rocket and they left Earth.
