This may be a "how to remove excess transparency from image of an actor" issue. Make a copy of image and then use my Image Transparency Adder/Trimmer scenario to remove excess trannparency from image. Just load the image and immediately save it. All excess is automatically removed.

It is downloadable. Click on the big green "Open in Greenfoot" button and save it on your system. Then you can open the file with your greenfoot application and use it there. You can even "Share" it to make an application file out of it (select the tab) so that you can use it without opening greenfoot first.

Ah. If you are using a newer version of greenfoot (any that has the greenfoot.Color and greenfoot.Font classes), then that scenario will not work. Maybe sometime soon I can re-upload it with an application already included in the folder.
