Sunny Scribens was inspired to write this song by her husband's research in human-robot interaction and her childhood spent playing outside in Tennessee, USA. She has also written Space Song Rocket Ride and Baby's First Words (with Stella Blackstone) for Barefoot Books. She lives with her husband and daughter. Hui Skipp was born and raised in Taiwan, and has training in everything from sculpture to fine art to TV set design. When she's not creating art, she can usually be found curled up with her little black cat. This is Hui's first project for Barefoot Books. She lives in London.
