[SligStorm]

I've tried to go through that trapdoor in Zulag One countless times, but have failed. The way I see it is that this person might've just edited the video to make it seem as if they went through. I think the reason why there's a bird portal there is because, when you return to Rupture Farms, that trapdoor leads to a secreat area, and I believe the bird portal is located somewhere around where the video showed it.

I have just went through that trapdoor, and it is not too difficult... just pull the lever from it's right side and then jump there. But, there is nothing there, and you die when you jump. But that was already know before, because of the sound that the slig makes when it falls there.

See.. my video is NOT Edited :P
