: Normally, Whismur's voice is very quiet - it is barely audible even if one is paying close attention. However, if this Pokémon senses danger, it starts crying at an earsplitting volume.
; [[Pokémon Sapphire]]
: Whismur is very timid. If it starts to cry loudly, it becomes startled by its own crying and cries even harder. When it finally stops crying , the Pokémon goes to sleep, all tired out.
; [[Pokémon Emerald]]
: Its cries equal a jet plane in volume. It inhales through its ear canals. Because of this system, it can cry continually without having to catch its breath.
; [[Pokémon FireRed and LeafGreen]]
: It usually murmurs, but starts crying loudly if it senses danger. It stops when its ear covers are shut.
