The Hudson River is a river flowing through the U.S. state of New York. The last stretches of the river flow through the interstate border area between New York City and the state of New Jersey, emptying into the Atlantic Ocean at Upper New York Bay. The boroughs of Bronx and Manhattan directly border the Hudson River proper.
In the original 1989 videogame, Shredder has placed bombs in the river, and the Ninja Turtles must dive into the river and disarm the bombs in time before they go off.
In the 2003 TV series episode Prodigal Son, Leonardo is seen swimming in the river.
