DD and Bubbles are so great together! TY DD for taking the time and patience for your 4H project! Bubbles really picked up on depressing the key until it made a sound! At the Fair years and years ago there was a White Leghorn that would hit the lighted keys on a piano and each time she did a treat rolled out over the piano key. She played some nifty little tunes to get those treats but Bubbles does it without having to get a treat every single time!
