From Bulbapedia, the community-driven Pokémon encyclopedia.
Perish Song (Japanese: ほろびのうた Perish Song) is a non-damaging Normal-type move introduced in Generation II.
After 3 turns, all Pokémon that were on the field when Perish Song was used will faint unless they switch out. Perish Song does not affect Pokémon with the Ability Soundproof. If a Pokémon switches out with Baton Pass, Perish Song will still be in effect on the Pokémon switched in, even if it has the Ability Soundproof.
Any Pokémon in the player's Rescue Party affected by Perish Song will faint in 3 turns.
However, it can be prevented by entering the stairs to the next floor or by sending home an affected partner before the third turn.
It can also be prevented via any move, Ability, or item that heals all status effects (as opposed to a particular status effect), such as Heal Bell, Shed Skin, or a Heal Seed.
