Yes, Pensie Pinkies were hollow, pink rubber balls, just like Spaldeens. But Pensie Pinkies were a lot softer, maybe because they had less air in them, or maybe the rubber was thinner. In any case, because they were softer, Pensie Pinkies were easy to “fluke” (put a spin on the ball by squeezing it between thumb and knuckles as you tossed it. (Very good for Box Baseball.) I don’t recall any sponge rubber ball. You’da got kicked out of the neighborhood for that.
