During the development of Dark Souls, a popular tactic among the development team to go past Blighttown's Blowdart Sniper enemies (who can inflict the player with Toxic, a poison effect that gradually reduces the player's health) was to use the Dung Pie item to inflict Toxic on yourself already. This is because the Toxic effect from Dung Pies are much milder and the Toxic effect in general does not stack. This was not intended, but was kept in because they felt it added extra depth to the game.
