The S.S. Tortle is a ferry that appears in SMG4 and Sunset Paradise. Like in the name, it is a non-propelling ferry that is pulled by a sea turtle, wearing a sailor hat. The ferry sails on the Mushroom City-Port Aurora route.
- The ferry is different in appearances as it changes from SMG4 to Sunset Paradise after passing the fog. In SMG4, it is a generic GMOD ship pulled by a realistic sea turtle. In Sunset Paradise, it has a more cartoonish appearance.
