Sensation Comics, Vol. 1

In Florida, Diana Prince's Ladies Club throws a luncheon in her honor, where she meets Selfa Modern, a glad-handing, social-climbing phony. Mrs. Modern gets word from her household staff about a dangerous situation that her children have gotten into, in the process of running away from home, but she cavalierly brushes it off. Diana, in contrast, goes into action; she steps out of the room, changes into Wonder Woman, scoops up the childrens' nursemaid Dellie, sprints to the riverside, and dives in. The river is teeming with alligators, the children are in a canoe, and it is right now in the process of getting tipped over! Wonder Woman outswims the reptiles and reaches the canoe in time to pull off a gator-wrestling rescue and whisk the children back to shore. Mrs. Modern is completely a self-absorbed witch about the entire affair, is now spending some time being bedridden with "nervous shock," and absolutely wants nothing to do with those mischievous children of hers. Wonder Woman persuades the kids to not attempt another runaway, and they promise her they won't. Then Diana speeds back to her club, arriving just in the very nick of time, to be introduced, as "America's Number One Woman Secret Agent".

The next day, before leaving Florida, Diana Prince learns that little Babs and Lonny Modern haven't woken up that morning, and that their doctor is mystified as to why. Wonder Woman rushes to their house, sits between the childrens' beds, and takes their hands, then puts herself into a trance; soon she has joined them in "Grown-Down Land". The infantile authorities in Grown-Down Land judge Wonder Woman to be an adult and rule that she must be imprisoned, and must take a dose of "Grow-Down Syrup," a magic medicine. The toddlers tie up Wonder Woman with her own rope, and have her do some tricks for them, then send her off to the big world, to kidnap Babs and Lonny's parents and bring them back to Grown-Down Land. So she does that, abducting Selfa Modern right out of her own dressing room, then carrying her to Frank Modern's office, and scooping him up also, for a quick return to Grown-Down Land. In recognition of this deed, the Queen of Grown-Down Land awards Wonder Woman the Order of Distinguished Service Kiss, and a brisk spanking with a hairbrush.

Meanwhile in the big world, Steve Trevor and Etta Candy have heard that Wonder Woman has contracted a strange sleeping sickness, so they fly to Florida to help out. The situation at the Moderns' house reminds Etta of an earlier adventure of theirs, in which she and Steve had simply gone to sleep, and found themselves in a strange dreamworld. They decide to repeat that technique, and soon find themselves in Grown-Down Land. Meanwhile Grow-Down Syrup has taken effect on Wonder Woman (who now looks and feels about 9 years old and calls herself "Wonda") and on Frank and Selfa Modern. All of them soon find themselves playing tag and romping like children. As the magic medicine has done its work, little Babs unties Wonda's magic lasso and sets her free, because only adults can be slaves in Grown-Down Land.

By this time Steve and Etta have arrived at the gates, and the guards let Etta in, but not Steve. Wonda ropes Steve with her lariat and declares him her slave. Commanding him not to untie the knots, Wonda leaves him parked outside the prison, as night falls. Some of the children head for their beds, others want to play all night in a well-lit playground. Etta puts a penny in a light socket and blows the fuses, darkening the playground, sending fear and panic thru many of the children. Wonda unties Steve, and he puts a penny into the fusebox, (dangerously) restoring the circuit and re-lighting the area. Now all the children are crazy about Steve, and the girls think he's handsome. This is when Wonda realizes that she can grow back to her usual size and age, just by exerting her imagination. But once she's done so, she realizes Grown-Down Land is not real, so she hastily grabs all four of the Modern family, and races to get them back home, before they realize the same thing. It works; and soon Selfa and Frank have new and improved attitudes towards child-rearing and togetherness.
