#Siamese #Alien Meet the Henson family. Once a family of 5 and then 7 (now 4), It's just everyone's favorite MEAN alien and his twin half-alien girls. Their mom had a kid when they met and she discovered his secret when they decided to try for another one... fun. Shortly after she decided Alien wasn't her flavor anymore and birthed twin half vampire girls... needless to say he only kept his own kids, though she did try to leave her 1st son with him without permission. GOOD RIDDANCE
