Put your left fingers on A/W/D/Z/C and right fingers on arrow keys. Use left hand to choose a puppet part and right hand/arrows to move the part. If you just press arrows you can move the entire puppet left and right.
A special thanks to my Learning Creative Learning classmates @hayallerini_kodla for designing this wonderful macrame character Ropi and @kolmn for a physical marionette which gave me the idea to bring Ropi to life in Scratch.
