A passage from the story itself illustrates Rikki-tikkis' curiosity better than anything I could say...
"He nearly drowned himself in the bath-tubs, put his nose into the ink on a writing table, and burnt it on the end of the big man's cigar, for he climbed up in the big man's lap to see how writing was done. At nightfall he ran into Teddy's nursery to watch how kerosene-lamps were lighted, and when Teddy went to bed Rikki-tikki climbed up too; but he was a restless companion, because he had to get up and attend to every noise all through the night, and find out what made it."
