The Water Planet Aquarius (originally Aqualiss) is the water star of the nearby galaxy in Milky Way Wishes. It can be considered the second planet; its neighboring planets are Floria and Skyhigh. Most of the star's surface is ocean. What little land there is, is tropical and features vegetation. Most of Aquarius's civilization is underwater, found in air bubbles. The planet is similar to Atlantis in some ways. Aquarius is well known for the maze it features in its fourth room.

In Star Fox Zero — The Battle Begins, Slippy Toad reads a Nintendo Magazine. The name Aqualiss appears on the magazine's cover, alongside Floria, Mecheye, and Halfmoon. These are direct references to four of the planets in Kirby Super Star's Milky Way Wishes sub-game.
