Rikki-tikki-tavi is a mongoose who is trying to protect the bungalow and garden from two cobras and in the end he defeats the cobras and no harm will ever come to the family or their bungalow and garden ever again.
Darzee and his wife
Nag and Nagaina are two cobras who try and invade the familys garden but rikki-tikki-tavi does not let that happen.
Teddy is a little boy in a british family who lives in the bungalow that Nag Nagaina are trying to invade.
The Father and Mother
Darzee and his wife are both tailorbirds. Darzee is a song bird and writes songs for Rikki-tikki-tavi and his victory. His wife on the other hand is practical and levelheaded as she knows that she must help Rikki-tikki-tavi by distracticing nagaina so the mongoose can destroy the cobras nest. In a way, both birds take on the role of foil for rikki-tikki-tavi.
Chuchundra is cowardly and skittish but he does help in the battle against the cobras by telling Rikki-tikki-tavi that Nag plans to attack the bungalow at night.
The mother and father are a typical duo. The mother is a bit timid when it comes to all things nature. The father is a typical father, knowledgeable and practical and while the mother is freaked out by rikki-tikki sleeping with teddy but on the other hand the father understands that it is totally okay
