Electroplankton (Japanese: エレクトロプランクトン, Hepburn: Erekutoropurankuton) is an interactive music video game developed by indieszero and published by Nintendo for the Nintendo DS handheld video game console.

The first edition of Electroplankton in Japan is bundled with a set of blue colored ear bud headphones.

Performance mode allows the user to interact with the plankton through use of the stylus, touchscreen, and microphone.

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.

[1] 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.

[citation needed] Electroplankton was re-released in Japan, as part of the DSiWare service exclusive to the Nintendo DSi system in 2009.

[citation needed] 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.
