Hidden Items are items in Castlevania games that usually can only be used for points or collection that are hidden in the game, usually only obtainable by performing specific actions. In most games, these items can be treasures or mascots of other Konami franchises.

Hidden items first appeared in the original Castlevania game. They would rise up from the ground when Simon walked over a certain area or knelt for a certain time in a specific spot. Simon then had to hurry and collect them before they disappeared. Hidden Items would return in that game's remake, Castlevania Chronicles. Normal items, such as food, weapons, money bags etc, could be obtained in unusual ways in Castlevania: Rondo of Blood, such as by ringing a bell. Methods like these would become common ways to obtain hidden items in later games. Castlevania: Harmony of Dissonance hid a large collection of furniture in the game that could be used to decorate a special room. Hidden Items involving treasures or mascots became a regular feature of modern Castlevania games starting in Castlevania: Dawn of Sorrow and would also appear in Castlevania: Portrait of Ruin, Castlevania: Order of Ecclesia, and Castlevania: Harmony of Despair.

Castlevania: Dawn of SorrowEdit

After a long absence, traditional Hidden Items (treasures) appeared in Castlevania: Dawn of Sorrow. Konami Man also appeared as a hidden item, the first mascot item since the Moai statue, which could also be considered a treasure.
