I found this out from another Pokémon site I go to, so I'll copy and paste the article that the person found.
The White Hand Sprite
Known in the code as WhitHand.gif, this was scripted to appear as a Pokemon on the third floor of the Lavender Tower. It is divided into four separate animations: an introduction (the "cry" a Pokemon unleashes before a battle), an idle, and two attacks. These attacks are unknown, as they are listed simply as "Fist" and "Brutal". While viewing the animation has been proven to be hazardous, viewing the frames of the model has been proven to have no adverse effects. The White Hand is depicted as a shriveled, slightly decayed hand, with surprising attention to detail: flesh is peeling back from the bone, and several tendons dangle realistically out of the wrist. The first attack is the hand balling into a fist, then swinging forward. However, the "brutal" animation is missing several frames: The hand seems to open up, then cuts out. After a few seconds, it reappears, closed again. No record has been found of these missing frames.
Ghost Animation
The Ghost Animation, coded as Haunting.swf, was intended to be placed in several areas throughout the tower, including in the center of a path on the second floor. However, players cannot interact with it, leaving many to believe that it was intended as a "background feature". The ghost animation as well must be viewed in individual frames. It is comprised of 59 frames total. However, after extraction, around half of these frames have been revealed to be the standard ghost model used in Pocket Monsters. Around a quarter of the remaining frames are comprised of static, to produce a "fading" effect. However, interspersed with these bursts of static are several frames of screaming faces, along with images of a skeletal man in a cloak (hypothesized to be the Grim Reaper) and of several killed corpses. The meaning behind these are unknown- While under oath before the Video Games Commission Board, Lead Programmer Hisashi Sogabe testified as to having "No knowledge as to where these images surfaced." Out of all the phenomena associated with LTS, this animation is the most speculated on: In his thesis "Video Games and The Manipulation of the Human Mind", [viewable in appendix C] Dr. Jackson Turner argued that the images were intentionally placed in. Due to their brief time appearing on the screen, and the graphic nature of the frames, Turner theorizes that these were meant to subliminally influence players into becoming more frightened by the disturbing surroundings.
The Buried Alive Model
Often referred to as its code, the Buryman script, the Buried Alive Model was to be found on the final story of the Pokemon Tower, in what has now been replaced with the Marowak ghost. According to the scripts assigned to it, the Buried Alive model was intended to be the "boss" of the tower. Once reaching the top floor, the following conversation would have taken place.
Buried Alive: You're... Here.
BA: I'm trapped...
BA: And I'm lonely...
BA: So very lonely...
BA: Won't you join me?
After this, the battle would have been initiated. Once in
"battle view", the Buried Alive model appears to be a decaying human corpse attempting to crawl out of the ground. It has been programmed to have two White Hands, a Gengar, and a Muk. Strangely enough, a protocol for the Buried Alive's actions after it was defeated were not written. In the case of the player defeating him, the game would freeze. However, a specific ending was written by an unknown programmer upon losing the battle. In this ending, the Buried Alive was to have stated, "Finally, fresh meat!" followed by several lines of gibberish. He was to have then dragged the player character into the ground surrounding him. The scene would finish with a typical "Game Over" screen; however, in the background, an image of the Buried Alive character devouring the player was to have been shown. Especially strange are the protocols for after this scene. The cartridge was to download this image to the small internal memory contained in the Gameboy, overwriting the title screen that normally accompanied a Gameboy turning on. Instead, whenever it was started, the player would view this image as the sound file staticmesh.wav was played. The intended purpose for this effect, unlike many of the other factors leading towards LTS, is unknown.
Pathology Detail -- "Lavender Town Tone"
The predominant symptoms related to what would become known as the "Lavender Town Town" included headaches and migraines, bleeding from eyes and ears, mood swings and irritability, addiction to the games, unprovoked violence, withdrawal and unresponsiveness, and in approximately 67% of cases, suicidal tendencies. However, these symptoms only manifested in children between the ages of 7 and 12 years old who had reached the area in game known as "Lavender Town", most of whom were revealed to have been wearing headphones or earphones while playing the game (see Appendix A [here]).
As it turns out, the developers of the Lavender Town area had sought to make an area that would "leave an impression on the player", according to Seki Uchitada, who was a member of the development team. Seki claimed that at the time of development, a number of the team were interested in making Lavender Town a little different to the rest of the game.
"The Pokémon Tower is a visible result of that," Seki told ゲームの次元 ("Game's Dimensions" Magazine) in an interview earlier this year. "That, and the fact that Lavender Town is so different from all the other cities in the game: it is smaller, it has fewer people occupying it, it didn't have a gym... and, of course, the music was very, very eerie. In fact, in the first version of the game, we were told to slightly change the song played in the background of Lavender Town ... because our manager told us it would make children upset. The music used in subsequent versions is different."
Either Seki was unaware of the full impact of the Lavender Town Tone, or was vastly under exaggerating how "upset" children would get - no more is said of the music in the article, but there are mentions of Lavender Town's other macabre features (see below).
What Seki failed to disclose to Game's Dimensions Magazine was that the music used in the first-wave release of Pocket Monsters Red and Green was formulated out of an experiment in "binaural beats": using slightly different frequencies of sound, each frequency played in one ear through earphones or headphones, various psychological effects can be induced upon the listener. In most versions of the first wave releases, this resulted in the player feeling uneasy, apprehensive, and mildly disturbed. However, for upwards of two-hundred children, it provoked a variety of disturbances in the brain that went undetected purely because it was undetectable by fully developed human ears - instead, only children fell victim to the tones, resulting in psychological and physiological problems that in some cases led to death - many of which were suicides.
