The pink notes are one of the most important items found in the anime Onegai My Melody.
Power
There are 100 pink notes in need to be collected. Only Maryland animals can see them as the Black notes. Despite they are got by similar ways, they have a different effect. They power up My Melody rather than Kuromi. She needs those notes to save her world and Uta's world. Each time a dream of a human becames true, a note will appear and will get inside the Melody Box.
