Piano Animal is an arcade game on Aqua Venatus in which you will hear different animals playing scales with their own calls. You first choose an animal such as cat, bird, fish etc, then you click the piano to see what their calls would be like on different gamut. You will find it is quite interesting. Enjoy it!
