Watercolour is an action-adventure platform video game for the Nintendo DS developed by Dollhouse Games and published by Nintendo in 2007. The game focuses on the protagonist, Muriel, a mystical sea spirit with the ability to manipulate and control colours. When Neptune takes away the colours of the world as punishment for his polluted oceans, it's up to Muriel to retrieve them from his seven corrupt children.


Watercolour is a 2D game action-adventure platform video game. The game is separated into two different modes:

Overworld Mode

A top-down, central hub where the player progresses the story and interacts with the Merpeople of the said area, purchases items from the item shops using Sand Dollars collected in Adventure Mode, and accesses levels.

Adventure Mode

Selecting a level from the Overworld Mode hub opens to a side-scrolling platformer with 80 levels. Here, the player battles enemies, rescues Merpeople, and collects items. Players can paint platforms that allow them to progress through the level using the stylus. The 10th level of each Sea is where they battle the boss, one of Neptune's children.


There is a legend that states a sea spirit called Muriel gave colour to the Earth, and that she comes to check the colour spectrum every million years.

Neptune once ruled over the seven seas peacefully, living in harmony with the people at land and people at sea. After years of living peacefully side-by-side, the people of the land became selfish, dumping their waste in Neptune's oceans. This continued for many years, making life for the Merpeople hard, they became riddled with diseases and were harmed by many of the waste the humans left at sea. The oceans became so polluted the corrupted Neptune's seven children, so as punishment, he stole all the colours from the world and placed them inside eight Mystical Shells, giving seven to his children and keeping one for himself.

The new millennia had rolled by, and Muriel was to awaken from her deep-sea slumber. Emerging from her sacred clam, she was greeted by a world without colour. She later learns of Neptune's punishment and decides to help by clearing the world's oceans and saving his children. She first saves Adrian, who tells her of his father's recent corruption and location of his other brothers and sisters. Muriel sets out on a quest to save Neptune and return colour to the Earth.
