Electroplankton BeatnesDSiWare

Beatnes are curious plankton with geometrically shaped heads that form vertical strands like seaweed.

Their bodies are made up of eight sections, each featuring a distinctive diamond-shaped tail. The sound of a Beatnes can vary wildly depending on which segment of the body is tapped. However, all of the sounds closely resemble the short-wave and triangular-wave sound effects from a Nintendo Entertainment System™ sound chip. When Beatnes are tapped in time with a rhythm, they continue to repeat the sounds in perfect time for a short period.
