This is from “Rikki Tikki Tavi” in The Jungle Book.
Rikki is a young mongoose, exploring the world, who finds himself in the over-grown garden of a big old bungalo.w. He makes friends with the fsmily who have just moved in. As is his nature he makes war on the two great cobras who live there. Here he is attacking Nag, the male.
Later he will face Nagaina, the female, just as big, and just as deadly.
