I had wondered in my childhood about the straight lines found on the muddy soil: it was raining the previous evening; who would have drawn them overnight! As I grew up, I understood who it is: the lines were drawn by worms, the Earthworms! (term and names: Lumbricus terrestris, Rain worm, Night-crawler, Angleworm, 'Munpulu' in Tamil). Though these brownish worms are found in rainy season, their presence in summer can also be inferred by the mud-disrupted lines on the irrigated farm grounds.
At evenings, whenever I walked on the outskirts of my hometown, I used to see small birds flying on the sky in darts here and there. I had wondered in my school days whether they are insects, bats or birds. These arrow like flying things are only birds known as Asian Palm Swifts (Cypsiurus balasiensis, 'Panaimara ulavaran' in Tamil).
In my school days, I have heard my elders tell stories about mongoose apart from that popular story, 'Riki-Tikki-Tavi.' One of such stories is here: the mongoose stole daily a hen from the hen house and left out the hen's body after eating its brain! It simply entered into the hen house burrowing down the earth next to the fence!
