4chan leak and Jellyfish UFO

I’m reposting because I’ve just found some photos! I’m attaching them.

A few months ago, a guy on 4chan claimed to be leaking top-secret UFO photos. The photos were high quality and up close, but the UFOs were so grotesque that everyone thought they were fake; they looked like weird humanoids, with static iron limbs.

Now when I see the jellyfish UFO it reminds me furiously of those images, but I can’t find the thread in question. Does anyone know what I’m talking about? I’m looking for an archive…
