if you look boy have willies and girls dont
Some gooey aliens dont have willies so you can tell by looking at the aliens back and if there is a slit deep down its a girl if not its a boy.
also some gooey aliens are he-she's.
Sky is either for a boy or a girl. I know many males AND females with this name
You put in the fridge or put a girl back to back witha boy and rub them together or rub goo on a girls back daily.
they do it at nightrube your aliens on the for five min's in 2-4 days it shoud be pregnant. (if its a boy no it wont get pregnant)
Hephaestus, or Vulcan, is a boy, not a girl.
Bullets, the weakness of all beings with the exception of Bruce Lee.
the boy alien has a sticky up bit between its legs the girl is flat
Not that I know of. All the pregnant ones I have had have been female. I highly doubt that a male one can.
look in between its legs and if its got a lump its a boy if it hasn't its a girl
say "you look fat!" if it kills you then it's a girl
it get an inch bigger
it got holes if it a girls x

You have to look inbetween the legs!If it has nothing there its a girl,if it has something there its a boy!
The human race has not yet seen an Alien and still do not know if they exist, so nobody knows if they have genders and if they do we do not know how to tell one from the other.

If it is a boy it will have a penis (but only when its a baby) Girls Have Nothing if its older girls have different necks to boys
