The images presented in figures 1 and 2 were created from an original image from the story and edited using GIMP (GNU Image Manipulation Program). Although GIMP is an advanced application, it was easy to use and very useful for: i) extracting the characters with transparency from the original image and to ii) fulfill the background after removing the duck. For this purpose, we used the GIMP Foreground Select Tool and Heal Selection which are very easy to use and yet very powerful.
