The Three Alien Humanlike Boys

They thought they have landed on earth safely, without anybody noticing them. They were rejoicing and prancing around at the Singapore River.

I was there. I saw them. I hid behind the bushes, looking at them. Though they were aliens, they really look like humans.

I've read somewhere that aliens can shapeshift.

Evil twin, "How can you tell if they're aliens if they shapeshift and take the form of other people's faces?"

I'll be going to the library to do some research on them. Meanwhile, beware of them.
