When Noiwag are close to their Trainer, the pattern on their stomach focuses soundwaves so that Trainers who are hard of hearing can hear better. They are small enough to fit in most backpacks and can even function underwater.
It is possible to see this Pokémon's spiral innards right through its thin skin. Even a robust wrestler will become dizzy and unable to stand when exposed to its 200,000-hertz ultrasonic waves.
