Water people

Water people are a mysterious race of liquid humanoids in Magical Vacation and Magical Starsign, native to the Water Realm of Kovomaka, as well as the Holy Water Pyramid on Cassia.

History
Prior to the events of Magical Vacation, the water people were driven out of their realm after enigmas invaded, causing them to be flung across the universe and ending up in foreign realms. Those who were sent to the Dark Realm created Akvavit Castle on the edge of Muy Mot Desert by draining its rivers. Later on in the game, some water people could be found in the Abyssal Realm, namely May Village and the Abyssal Corridor, waiting to be reborn as something new.

Over 800 years later in Magical Starsign, the last remaining water people occupied the Holy Water Pyramid, devoting their lives to protecting the water millennium gummy. Unfortunately, all of them were killed during the Space Police's assault on the pyramid, thus making water people an extinct species. Their extinction was further confirmed in Fondue's trivia, suggesting they may have beeen extinct in the Water Realm too.

Physiology
Water people, as their name implies, are humanoids made of pure water. They have round, bubbly heads, big hands, and faded eyes. From the waist-down, water peoples' bodies expand into puddles, and they move around by wobbling back and forth. The language they speak is called Aquarim, which in Japanese, is scrambled hiragana and katakana. Only those fluent in Aquarim, such as Blueberry, can translate it into the common language.

Trivia

 * "Water people" is both the singular and plural term used for the species.
 * According to a water people in Akvavit Castle, they were all one colossal entity prior to being split up by the enigmas.
 * It is likely that water people were planned to be alive and interactable Magical Starsign, as dialogue portraits exist in the game's files.
