Why is Pacific Tree Octupus a hoax?

It isn't. The website was not only a haox, but also a joke. It said that one of the tree octopus' enemies was SASQAUTCH. Also, it never even mentioned this: HOW CAN AN OCTOPUS BREATHE ON LAND? Now, if you are talking about that expierement they did with a class of kids, it just shows how they will believe anything they read.
