The river isn’t as scenic as it looks
This uncle's house is by the river. One day, while he was cleaning the riverbank, his tools fell into the water. He reached out with his foot to grope around when a ferocious creature grabbed him by his leg. He cried for help in agonising pain. His wife came running and hit the beast to help him escape its tight bite.
The croc retreated back into the river, but soon uncle's flesh started to dissolve, the creature's enzymes penetrating his body. He was rushed to the hospital, fighting for his life. Uncle did survive, but lost his leg and thereby his livelihood of driving a three-wheeler.
