Giant cobras turn out to have many useful pieces! She rips out its fangs and molds them into sharp knives, then uses those to somewhat clumsily hack off long strips of its skin, which she pinches together again like a chef sealing a pie crust and rubs with her hands to get the ick out of the insides. Once she's got enough of that to work with, she wraps some of it around her arms to make sleeves, and some around her waist to make a knee-length leather skirt, with a belt on top to hold sheaths for the knives.
At this point both her arms are red to the elbows with snake blood, and she is muttering a steady stream of curses about the heat and the materials and whatever unknown force brought her here in the first place. Nevertheless, she keeps skinning the snake, and confidently if messily butchers its remains until she has a heap of bloody bones and a snakeskin backpack full of meat. Then she rolls scraps of snakeskin into a long thin rope, lines up all the sturdiest ribs side by side, and weaves the rope through them to form a long string of snake ribs which she can then bundle up and tie to her pack.
"Okay, fire," she says, flexing sticky red fingers and grimacing. "Fire needs wood. Wood needs tree. Where tree?"
