Playskool Little Wonders Pop-a-tune ($39.99) was a favorite toy of my elder grandson, but had disappeared from store shelves for some time. It’s back, and just as good as I remember it. The six keys can play silly noises or musical notes. Regardless, and even if you turn off the sounds, every time you press a key the balls under the clear plastic dome go flying! The popping balls offer enough visual stimulation to keep a one year old coming back for more, as they learn about cause and effect.
