You can find the girl lamb Piano ingame in HKO in the Moulin Rouge in Paris very close to the east exit of Paris (on the right side of the map). You will first have to locate the key to the house she is sleeping in and then help her find something she lost.
My Sweet Piano is My Melodys best friend. She was born on July 6th in Maryland. She has fluffy baby-pink wool and loves Meringue cookies. The little lamb Piano is tender and kind, she loves chatting with Melody while picking flowers the most.
