In several regions snakes!

The geographical breadth of these incidents is expansive. In Thailand, a country where diverse snake populations coexist with densely populated urban centers, one of the most widely reported cases involved a man who was targeted by a twelve-foot python. The serpent had coiled itself within the plumbing and struck while the individual was seated, resulting in a severe bite to his testicles. The ensuing struggle to free himself from the powerful constrictor required significant effort and emergency intervention. While the victim eventually recovered, the incident underscored the sheer size and strength of the reptiles capable of navigating residential pipes. Pythons, being semi-aquatic and highly flexible, are particularly well-suited for such incursions, often entering through roof vents or damaged sewer junctions.
