Read this: While no other Timely character would achieve the success of these "big three", some notable heroes—many of which continue to appear in modern-day retcon appearances and flashbacks—include the Whizzer, Miss America, the Destroyer, the original Vision, and the Angel. Timely also published one of humor cartoonist Basil Wolverton's best-known features, "Powerhouse Pepper", as well as a line of children's funny-animal comics featuring popular characters like Super Rabbit and the duo Ziggy Pig and Silly Seal.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): What duo of kid-themed characters were featured in early Marvel issues?
Ziggy Pig and Silly Seal
