Just kidding! It’s artist Marlin Peterson trolling the Space Needle.
Artist Marlin Peterson painted a giant rooftop mural of arachnids in Seattle.
You can see them from high up in the space needle or even a plane.
The shadowing of the spiders make them look like real giant alien spiders taking over the roof of the Armory Building!
Watch this video which captures the whole beautifully eery process.
