Tapped to save the world by advertisement-spouting alien SPHDZ Jen and Bob (who resemble human kids), beleaguered fifth grader Michael K. continues his quest to recruit 3.14 million earthlings to be Spaceheadz lest the Earth be turned off. Even more beleaguered Anti-Alien Agency Agent Umber continues his quest to find the aliens in or near Brooklyn PS 858. Michael K. has some help in new friends Venus and TJ, but the whole group has to act as Big Buddies to the kindergarteners and help with their class play, while Spaceheadz General Accounting has given them one hour to get 1 million new Spaceheadz (thank goodness one Spaceheadz hour equals 700 Earth hours). Can they boost recruitment without giving themselves away? Will Agent Umber ever succeed at anything? Will the plumbing at PS 858 survive the surplus World War II rations the kids all eat? The second volume in Scieszka and Prigmore’s nutty, antic series offers more goofy fun with some pretty obvious setup for episode three. The integrated websites will be updated and supplemented to extend the laughs. CLINICALLY PROVEN entertainment for fans old and new! (Fiction. 7-10)
