You could create a "transfer" object, using the eyes images for it, to "carry" the ghost back to the ghost box. If interested in this idea, start a discussion thread.

@lordhershey, this is a copied scenario (it may or may not have any changes to it). The original is here: http://www.greenfoot.org/scenarios/189

She says she does not like it and she is not certain that it is very interesting. To 'unlock' the scenario, you re-upload it, making sure to uncheck the 'Lock scenario' checkbox on the Share dialog frame. This will allow users on the site to have access to the speed slider and they will be able to move actors around in the window.
