What do Sawyer, Carl and this BEAST have in common?

What th hell is this beast?
Can we say it eats Dharma Fish Biscuits? I wonder how many seconds it took this thing to discover how the mechanism worked? Also, is this thing making the noises we hear at nights, moaning with Sawyer and Kate that night, when I Love You's were passed around?

Or can it be Joop making the noise? Who's Joop? What's Joop? 105 years old? How long has this island been going on?

Who are these beasts we're talking about, more to come!!! Hanso Foundation have been busy. Thanks Rachel, or Persephone. Whichever
