Update or glitch fix please – Pat the Bunny Review

This is a wonderful app, my toddler loves it. The only issue I have is regarding the sound. A good minute into my toddler tapping around the app the music becomes jumbled and sounds pretty demonic (lol); it sounds like two tunes are playing at once; how can this be fixed? We are using an iPad Air 2.
