Metabat is unable to see during the time it's waiting to evolve. As such, it must use different methods to protect itself, such as hardening its shell or emitting ultrasonic waves.
If left alone, it will become despondent, leading other Pokémon to believe they can attack it. When they do, however, they tend to end up stabbed by its horn without Luvran even meaning to stab them.
Polihoot has a more difficult time walking than swimming or flying. When it needs to travel on foot, it tends to hop on one foot all the way to its destination.
