What in interesting variety of childhood reading memories! I was a Pokey Little Puppy and Tawney Scrawney Lion fan, too. Really enjoyed reading them to my younger sisters. But I think my faves were the series about a pair of twins — brother and sister — by I know not what author! They were The Cave Twins (my very favorite), The Dutch Twins and several others. They must have been published in the thirties by my recollection of the illustrations. And, no, I’m not THAT old! But my mom is.
