Well, in order for the Pillsbury Doughboy to actually disintegrate like that, you would have needed to eat his family members BEFORE he was conceived. Given that the Pillsbury Doughboy first appeared in 1965, we can subtract a few years off of that because he isn’t a newborn in his first commercial. Let’s say he’s about 7. 1965-7, that’s 1958. But we can assume that his pregnancy started about a year earlier, in 1957. So get the parents anytime before 1957, and it should work.
