There is a person on YouTube who calls himself Dr. Draw, he has some animations related to Dig-Dug but in these the inflation is not so explicit, even in the most recent of his animations the inflation, although it does explode, only remains as a shadow that leaves the viewer's interpretation of how it should have looked
He also publishes drawings, but it is rare to see him draw something inflated or a little fat
