"The Lavender Town Syndrome (also known as "Lavender Town Tone" or "Lavender Town Suicides") was a peak in suicides and illness of children between the ages of 7-12 shortly after the release of Pokémon Red and Green in Japan, back in February 27th, 1996.
Rumors say that these suicides and illness only occurred after the children playing the game reached Lavender Town, whose theme music had extremely high frequencies, that studies showed that only children and young teens can hear, since their ears are more sensitive.
Due to the Lavender Tone, at least two-hundred children supposedly committed suicide, and many more developed illnesses and afflictions. The children who committed suicide usually did so by hanging or jumping from heights. Those who did not acted irrationally complained of severe headaches after listening to Lavender Town's theme.
Although Lavender Town now sounds differently depending on the game, this mass hysteria was caused by the first Pokémon game released. After the Lavender Tone incident, the programmers had fixed Lavender Town's theme music to be at a lower frequency, and since children were no longer affected by it.
One video appeared in 2010 using ”special software" to analyze the audio of Lavender Town's music. When played, the software created images of the Unown near the end of the audio. This raised a controversy, since the Unown didn't appear until the Generation 2 games: Silver, Gold, and Crystal. The Unown translate to "LEAVE NOW"."
Of course, this legend is false as there were never any reports of children commiting suicde from the song. This legend actually scared me a lot as a child and it took me until I
was 10 to listen to the Lavender town [green version] theme without feeling a little sick. Another Lavender town related legend was "Buried alive" a supposed scrapped boss fight that would have had a decomposing corpse fight the player in the last level of Pokemon tower in Lavender town with a party of a Muk, Gengar, and two "white hands" and if he beat the player there would be a game over screen of the corpse dragging th player underground. Before battling the player he would say, "You're here...I'm trapped...and I'm lonely...So very lonely...Won't you join me?",, This one also scared me as a kid :p
