# Electroplankton

Electroplankton is an interactive music video game developed by indieszero and published by Nintendo for the Nintendo DS handheld video game console. It was first released in Japan in 2005, and was later released in North America and Europe in 2006. This game allows the player to interact with animated plankton and create music through one of ten different plankton themed interfaces. The first edition of Electroplankton in Japan is bundled with a set of blue colored ear bud headphones.

## Gameplay

The game offers two game modes: Performance and Audience. Performance mode allows the user to interact with the plankton through use of the stylus, touchscreen, and microphone. Audience mode is like a demo mode, which simply allows the user to put down the system and enjoy a continuous musical show by all of the plankton, although the user can interact with the plankton just like in Performance mode. The game does not save data of any kind, which prevents players from saving any elaborate or quality pieces. This problem can be overcome by connecting an audio recording device, such as a cassette recorder or a personal computer, to the headphone jack of the Nintendo DS.

## Development

Nintendo president Satoru Iwata explained that the unusual reason why director Toshio Iwai's name appears directly on the game's packaging is because he alone had created it. The game is the second collaboration between Nintendo and Iwai, having done so with Sound Fantasy for the Super Nintendo Entertainment System, which was never released. The developers considered including a save function, but opted not to because they wanted for the players to enjoy the game both extemporarily and viscerally. They believed that if a save function had been included, then the game would have been used more as a tool, where the player must open several additional menus and windows or must input file names to save. Another reason was that it would require a large volume of flash ROM and would take a long time to save and read the data in order to save the voice files for Volvoice and Rec-Rec.

## Release

The game made its first public appearance at the 2005 Game Developer's Conference, and later, an appearance at the E3 show. The game was released in North America on January 9, 2006; sales of the game were limited to online retailers and the Nintendo World store in New York City, though some other retailers chose to carry the game. For example, Electronics Boutique carried the game when it was released in Canada. It was released in Europe on July 7 the same year.
A release was planned by Nintendo Australia in late 2006 but never occurred due to, according to Nintendo Australia representatives, not enough space in the release schedule.

## Reception

Joystiq gave it 8.0 out of 10. Nintendo Power gave it 8.5 out of 10. IGN gave it 7.0 out of 10. Official Nintendo Magazine gave it 78%.
Kidzworld said that one of the most common complaints concerning Electroplankton is that the game offers no true way to save the audio created by the player.

### Legacy

Electroplankton is represented in Super Smash Bros. Brawl with its own stage called Hanenbow that is based on the Hanenbow feature. This stage also returned in Super Smash Bros. Ultimate. Several stickers and Spirits based on the game were in these two games.
