The Pacific Northwest Tree Octopus
I don't mean to spoil the fun, downvote me if this is not in the spirit, but it took me way too long to figure this out and others may be as slow as me and save some time by reading this comment:> The Pacific Northwest tree octopus is an Internet hoax created in 1998 by a humor writer under the pseudonym Lyle Zapato. Since its creation, the Pacific Northwest tree octopus website has been commonly referenced in Internet literacy classes in schools and has been used in multiple studies demonstrating children's gullibility regarding online sources of information.
