If your son has been bugging you to buy a Nintendo handheld console for him, this may just be the perfect copout. Introducing the Yoshi's Island water puzzle game. This faux DS Lite is filled with water and two buttons let you control streams of bubbles which will move tiny rings inside. The objective is to land those tiny rings into the right spots using your amazing bubble navigation skills.
We don't know if children these days are capable of having fun without a computer or (real) console these days, but this one should provide a wee bit of amusement--for all of 2 minutes.
