09 Supergirl — The Cave-Girl of Steel

Another fun story.I liked the opening part of the story with Supergirl saving the baby with the plastic bag, and the headmistress taking a lesson to get rid of the plastic bags and warn the children not to play with plastic bags.
Most of the rest of the story was Supergirl having a fun adventure in the distant past, as a young girl with super-powers would, and which young readers would enjoy.
The ending, with the prehistoric artwork depicting her fighting the fire-breathing sea serpent making her fret about her secret being revealed, which, in this early stage of her time on Earth, is a prominent theme in several stories. She must be really worried about that after Superman “exiled” her for revealing her existence to Krypto in the previous story!
