Skeletor will possibly return tomorrow with another theory

That weird claw thing that took Mommy Long Legs' head.

Oh

Those are 2 different games

But people have been saying that 1006 is something like Ennard, who is a mix of most of the SL animatronics.
In Poppy Playtime, Mommy Long Legs said that he'd make her part of him. Also, in the room with the Bonzo Bunny puzzle (conveyor belt puzzle, not Musical Memory), we see Huggy Wuggy's fur and a bit of blood on the walls. This is probably because when we knocked Huggy down, he managed to crawl through the vents and into there. 1006 probably found him and took Huggy to make him part of the experiment.
So, 1006 is an experiment somewhat like Ennard. Thank you for your time.

It's either that or Huggy
