I've found it!! Ethan and I decided that Robots is the theme for their new bedroom! We love the green, orange, navy and light blue color scheme! Now I have all the rooms on the 2nd floor designed (in my mind)!
Spotted! Max Grover's "Yellow Robot" Canvas Art for Kids http://www.oopsydaisy.com/store/shop/canvas-wall-art/yellow-robot.html in this awesome robot room for boys - chalkboard paint on feature wall for designing your own robot.
