A rogue spell-check program's bid to transform all life-forms into that eminently useful office item, the paper clip, touches off a fresh round of lunar lunacyPredicated on the entirely reasonable premise that eliminating all spelling and grammar errors everywhere would logically lead to the necessity of exterminating carbon-based life in the universe, this third series entry combines high stakes with daffy banter and daring exploits. CheckMate-a chipper, jumped-up editing program-has invented the Transmogratron, a giant laser that will fulfill its ultimate goals in both the cyber world and "meatspace." Facing challenges as random as prankster lunar unicorns and a disarmingly motherly Motherboard, scowling First Cat joins a motley crew of diversely carbon- and silicon-based allies, led by the pearlescent Queen of the Moon. They're in a race to the finish-diverted occasionally by, for instance, a relentlessly punny comic-book interlude featuring a pair of literal and figurative Pool Sharks. They ultimately triumph thanks to teamwork and moxie. Following a celebratory party and toasts to "new friends…and steadfast comrades" (and, of course, "MEOW"), the story's energetic, brightly colored panels close with a reveal of the next volume. ("I always hate it when comics end by announcing a sequel. SO CRINGE!" declares an authorial stand-in.) It can't come too soon.File under "laugh riot."(Graphic science fiction. 8-11)
