Supermuscleman and Doc Krok are at it again, and it's not just the galaxy they're out to ruin—it's Sardine and Little Louie, too! Get ready for the ultimate match-up as wits battle brawn in the best bout of this series. Yes, that's right—it's the Space Boxing Championship! The fearless cousins must go head to head with Supermuscleman, Chief Executive Dictator of the Universe, shrunken to enter the kids' matches, but just as muscley. And that's only the first of the ten stories contained in this book.

In a starred review of the first Sardine volume, Kirkus Reviews proclaimed, "With non-stop action [and] humor geared to multiple levels of cultural awareness . . . readers will find that, as Supermuscleman sneers shortly before gorily blasting his own foot, 'Resistance is futile.'"
