misadventures of two toddlers named Sugar Plumm and Cecil "Spike" Wilson, who possessed the ability to communicate via "baby talk" with each other and to other infants, but not to adults. It shared ideas concerning baby-talk with P. L. Travers' Mary Poppins novel; one notable feature was that all babies spoke the same baby-talk "language", allowing Sugar and Spike to speak with not only human infants, but baby animals as well. Another popular recurring feature was paper dolls of the two leads, with outfits based on designs submitted by readers. Mayer used his own children, Merrily and Lanney, as inspiration for the strip. In addition to the toddlers, their parents and adults, who were only seen from the waist down (Bill and Barbara Plumm; Harvey and Peg Wilson), recurring characters included: Little Arthur, a "big boy" too old for baby-talk. A spoiled brat and a ruffian, Arthur torments Sugar and Spike, but is invariably outwitted by them in the end. He is introduced in issue #17 (August 1958). Sugar's Uncle Charley, a bachelor and police officer who is a stereotypical "fun uncle", often playing with the kids and giving them gifts when he comes to visit. Bernie the Brain, a child genius who, despite being the same age as Sugar and Spike, is an accomplished scientist and inventor who speaks and understands "grown-up talk". When he first encounters Sugar and Spike, he requires a translating device of his own invention to teach him their baby-talk having already progressed past that stage, intellectually. He enjoys the chance to be a normal kid with Sugar and Spike, while the pair loves playing with Bernie's various inventions. The two often seek out Bernie when they encounter something they do not understand, particularly something involving grown-up behavior. Bernie made a cameo in Crisis on Infinite Earths #9 watching Clark Kent on the WGBS television news report on the Crisis and he appears to be very concerned about what is going on. Revival Writer Keith Giffen and artist Bilquis Evely brought back the characters as adults in 2016, starring their own adventures (among other characters) in the new ongoing series Legends of Tomorrow. At the time of the announcement, DC Comics Co-Publisher Dan DiDio said of the Sugar And Spike series: "They're not spoiled kids anymore, but they're older and they're operating as private investigators handling problems and mysteries that the superheroes can't handle themselves".
