50th post! Let make it interesting! Alien Invasion???

This is something I bump into when I was surfing the internet yesterday..
Yesterday just when I was browsing YOUTUBE,
I came across this video..
At that time, it was only about 1million ++ viewer..
Today, it got almost 4.5 million viewer!!

Check this out!
Well hidden inside a sewer...
Looks like it's breathing, expanding and shrinking..
Some kind of alien's egg waiting to be hatched??

Well, you decide..
