They all risk spoilers, though... So it is highly recommended to do it after fully experiencing the game!
The first way is to use debug mode. Further tips: 1.Spawn a ghost. 2.Be eaten. 3.And then... wait.
The second way is to directly find the image file of it. To find them, we need to go to the "resources\sprites\" folder and select the folder of the ghost you want to see... And then there it is!
By the way, the images found in this way are without any background. It has only "ghosts". and...Japes sometimes.
