What if a huge cobra intrudes into your house and starts living there? 

Well, something similar happened with a Malaysian man.

Derrick Koh witnessed a massive cobra entering his home in the Batu Pahat District of Johor, Malaysia and all he could do was to film it.

At first, the snake was creeping around outside Koh's home, but it eventually found its way to the house's entrance.

The massive cobra slithered up the door and entered the home through an open window.

Koh called the fire department but they were initially unable to find the snake inside the home. 

Finally, after three days and two nights, Koh says the snake was removed from the home.
