The River is a scenery location in the game, Swimmy Sea, that was released on Version 1.0.
The River looks like an open-spaced river. The ground is made out of green and dark green pebbles with algae on it. It also has explosive mines and white monsters coming out of holes, all of this surrounded by gray rocks. Sometimes, there will even be a submarine on the ground with enemies in it.
- It is the 2nd most darkest environment, the #1 being The Deep.
- While being on the main page with this scenery, the logo will turn blue navy and turquoise, contrary to blue navy and white.
