I try – Secret of Treasure Mansion Review

I was also stuck. This may help! Once you go upstairs there are three doors but actually 4 paths. On the right side of your screen on the same the same side as the door that leads to the piano/harp room click on the wall to your right and closest to you. It will lead you to a new room. With 2 statues and dolphin fountain.
