Porter

Porter is a monkey that stands outside the train station in the Animal crossing and Animal Forest. He helps the player travel from town to town. He is the only the other way to save besides the gyroid. He has not been seen or mentioned after he did not appear in Wild World or any game further. It iss possible he was taken out because the taxi and the bus are more modern than the train. Also the gameboy island was taken out and kapp'n was probbably more popular than Porter so he was selected to run the transportation.
