Synopsis for Mary Marvel: "Mary Marvel and The Sinister Twins!"
Mary Batson has gotten direct hate mail from Georgia Sivana saying she’s rob the Gold Display in Lacey’s window and at high noon and that she can’t stop her! Mary decides to head out and keep her eye on the Royal Diadem there or if she should go find Georgia personally and calls SHAZAM to become Mary Marvel. Luckily, they’re both in the same area since Georgia launches a brick through the window and then starts shoving jewelry in her satchel to leg it around a corner into the park, but when she punches her out, she finds it’s actually a robot! The real Georgia mocks that she tricked her with this robbery, during which she’s going to steal a prized $1,000 orchid from the Flower Show! One town over, Georgia fires a chloroform insect-spray can, but Mary Marvel snatches it back and punches out this Sivana Girl, finding it’s also a robot. Georgia reveals had even further job she was pulling and that she’ll be following her robots everywhere! Mary Marvel worries about where she’ll strike next, but decides to keep guarding the Royal Diadem first. An elderly lady trying to sell flowers fires a chloroform at the guards carrying the Royal Diadem and snatches it from them, but Mary Marvel flies down and finds that it was the real Georgia in disguise. Georgia asks how she knew that she’d come after the Diadem, but Mary Marvel says she was always going to guard the Diadem specially, a facet of her plan that she hadn’t thought of. Later, Mary finds that Georgia wanted it to be “Princess of Earth,” but as usual, she failed.

Synopsis for Freshman Freddy: "The Good Skate"
Freshman Freddy is tripping and falling due to trying out roller-skates and not doing a very good job at it. He tells Ace and Stooge that he’s training to go roller-skating with Harriet on the lake that afternoon and Ace decides to pull a fast one on Freshman Freddy, telling him he’ll grab his own skates and teach him in a half-hour. Ace starts spinning Freddy to make him flail, but he ends up shoving Ace into the water. Freddy accidentally manages to dodge a furious Ace, who skates after him and runs headfirst into a tree. Harriet rides up and says that Ace probably deserved this and that he probably doesn’t really know how to skate at all. She commends Freddy for at least being open with how much he can’t skate and offers him a private lesson!

Mary Marvel flies them through the snow until she finds some hunters trying to take down the “reindeer” in the woods, but she warns them that it’s just a horse. She returns with Dobbin to find the sleigh has rolled down a hill, knocking out Freckles and sending the other kids crashing into a tree. Mary Marvel stops them before they hit it and fixes Dobbin back up to the sleigh after she find Freckles in the snow.

Synopsis for Mary Marvel, the World's Mightiest Girl!: "Mary Marvel and the Evil Bottles"
Mary Batson’s friend Teddy drops off some odd bottles they found in the junkyard and offers that Mary can have them. She opens one up and finds a tiny imp named Wart was trapped in the bottle and then bites her on the finger and runs off. He tries to lob a letter knife into her eyes, but she calls SHAZAM to become Mary Marvel and pretends to hide out on the bookshelf, but starts opening the other bottle to release his master, Sentour the Magician who loves casting black magic on people. He throws a magic ax at Mary Marvel as soon as seeing her, but quickly learns that she’s tougher than black magic and punches him in the jaw after the ax breaks on her body harmlessly. She asks how they got there and Sentour admits that a certain Ancient Egyptian wizard sealed him away, but pretends he doesn’t know his name, tricking Mary Marvel into calling SHAZAM! Wart offers that they should shrink her into the bottle, so they do so. Mary finds within the bottle, its soundproofing means she can’t call SHAZAM! Sentour and Wart soon take to the streets and Sentour tries to turn a kid’s bike into a bird, but it instead turns into a huge dragon and when he wishes it turned into smoke, it instead turns into feathers! Mary manages to crack the bottle by making it fall over and into the side of the table and calls SHAZAM to become Mary Marvel. She finds Sentour preparing to bewitch all of the Big Apple to earn untold valuables, but she instead grabs him by the hands and threatens him into both of them getting into the same bottle, returning them to their imprisonment and throwing them into the ocean.

Trivia
- Despite the cover, Freckles doesn't wear a comically-long and fancifully-colored hat, instead wearing a normal orange knit cap with a pom-pom. She also falls off the sleigh before an imminent crash into a full tree, instead of stump.
- Sentour's name is in reference to the fact that he is also a Centaur, which are presumably pronounced the same way.
