Introduction:
The baby boy was saved from the snake by a mongoose. A mongoose is a small carnivorous mammal that is known for its ability to fight and kill snakes.

Explanation:
The incident took place when the baby boy was playing near his house. A venomous snake approached the baby boy, posing a threat to his life. Fortunately, a mongoose happened to be nearby and noticed the danger.

The Mongoose's Actions:
The mongoose immediately sprang into action to protect the baby boy from the snake. It fearlessly attacked the snake, using its agility and sharp teeth to fight against the venomous predator. The mongoose's quick reflexes and natural instincts helped it outmaneuver and overpower the snake, preventing any harm from coming to the baby boy.

Reasons for Mongoose's Success:
1. Agility: The mongoose's agile body allowed it to swiftly dodge the snake's strikes and counterattack effectively.
2. Sharp Teeth: The mongoose's sharp teeth were instrumental in biting and disabling the snake, preventing it from biting the baby boy.
3. Natural Instincts: Mongoose species, like the Indian grey mongoose, have a natural ability to hunt and kill snakes. They are immune to snake venom and have evolved to be skilled snake hunters.

Conclusion:
In this particular situation, the mongoose played a heroic role in saving the baby boy from the snake. Its quick thinking, agility, and natural predatory instincts ensured the safety of the child. Without the intervention of the mongoose, the snake could have caused severe harm or even death to the baby boy. The incident highlights the remarkable abilities of the mongoose and its unique role in keeping snake populations in check.
