Noibat love nesting in any dark corner and are often found in chimneys. As the acoustics of the chimney make their ultrasonic waves ten times louder, if a whole flock of Noibat live together, a house can become unlivable.

Noivern no longer only eats fruit, now coming after Bug-Types that fly in the night. They particularly enjoy Venomoth, and won’t attack Venonat until it evolves. Noivern still seems to prefer fruit over everything else when it’s available though.
