This 1957 Charlton appearance of Happy the Magic Bunny is nothing special as this character's appearances go. What makes Happy interesting is that he is, in fact, Hoppy, the Marvel Bunny aka Captain Marvel Bunny! It seems that when Fawcett finally gave up the ghost in the wake of declining sales and annoying lawsuits from National/DC, Charlton picked up quite a few of their secondary non-superhero characters and series including their FUNNY ANIMALS title. Thus, Hoppy outlasted the rest of the Marvel Family by simply changing his colors, his name and his magic word! Many years later, of course, he would return to his origins at DC in the wake of SHAZAM!
