CD

A CD is a collectable found in Wario Land 4. Each level (excluding the Hall of Hieroglyphs and the Golden Passage) includes a hidden CD found in a CD box that Wario can find. Unlike the jewel pieces and the Keyzer, the CDs are not required to complete the game. Each CD holds a musical tune that can be played in the Sound Room, and the CD matches the color of the corresponding Passage it was found in.
