This is where the family and Rikki Tikki is introduced.
Nag, a evil snake ate a bird's egg. Rikki Tikki wasn't very happy about that and warned Nag but as he was doing so Nag's wife shows up and tries to bite him and just as she was going to he jumped in the air and didn't get caught.
The father killed Nag with a shotgun.
This is where Rikki Tikki killed a snake that almost hurt little boy.
RIkki Tikki took Nag's wife's eggs and killed all of them. Then he lured her in with one and killed her and the egg.
This is the end where everyone is now safe and doesn't have to worry about another snake again, thanks to Rikki Tikki.
