Electroplankton: Lumiloop

[DSiWare] Lumiloop plankton are curious, donut-shaped aquatic creatures. While stationary, they have the ability to spin at a very high rate of speed. As they spin, the Lumiloop emit unique sounds and a fascinating ring-shaped glow. Lumiloop plankton seem to always grow in clusters of five. They produce sounds at different pitches as they spin together, creating a beautiful harmony. This is called a pentatonic scale. Depending on where they live, Lumiloop plankton that produce several different sounds have been identified. [Nintendo]
