What are they worried about? The cobras are all dead. And if any more come, I'm here
"In the yard he heard the sad voices of two tailorbirds, Darzee and his wife. The birds were crying because a cobra named Nag had eaten one of their babies."
"Darzee's wife had more common sense. She didn't want young cobras around. She helped Rikki by fluttering around, pretending her wing was broken."
""What are they worried about?" Rikki-Tikki wondered. "The cobras are all dead. And if any more come, I'm here." Rikki-Tikki was proud in his own way, and he had a right to be. From then on, he protected the yard."
