You went potty all by yourself! Feel the same sense of achievement you did as a child with the Ecohime cellphone strap while simultaneously concealing any unpleasant noises.
Actually, the sound emitted by Ecohime is supposed to be running water, but as our leader Jason Chen pointed out "it sounds like a standing ovation." Hopefully, version 2.0 will embrace this theme with raucous applause and words of encouragement and praise. "I knew you had it in you!", "Way to be #2!" and so on. [Strapya via Technabob]
