Play Electroplankton Online
You poke and hum at these little musical creatures—some bounce notes off leaves, others loop your voice into beats—just pure, hypnotic tinkering with no rules.

Electroplankton is one of those weird, wonderful DS games that feels more like a toy than anything else. You get these little digital creatures—each with their own quirky behaviors—and just mess around with them using the touchscreen or microphone. Some bounce off leaves like musical pinballs, others follow lines you scribble while chiming notes. My favorite’s the Rec-Rec plankton—you hum or tap something into the mic, and it loops it back with this crunchy drumbeat underneath.
There’s no score, no goals, just this oddly satisfying sandbox where everything reacts to your pokes and prods. The Lumiloop ones are hypnotic—spin them fast and they glow brighter, slow and the sound deepens. Half the fun is discovering what each plankton does by accident. I remember tapping the screen randomly and suddenly the Nanocarps started swimming in perfect sync because I’d clapped without realizing.
It’s definitely not for everyone, but if you like tinkering with sound or just zoning out to something colorful and strange, this is a gem. The battery life warning in Audience mode is weirdly poetic—like the game’s reminding you nothing lasts forever, not even digital plankton concerts.
