Trivia

 * Despite being known as Sinnoh's fourth lake, the Town Map does not display the lake over the yellow area indicating the route.
 * This can be explained as the lake has been 'kept secret', and thus would not appear on any map.
 * The first time the player uses the Poké Radar there, no music plays; music plays on subsequent uses, however.
