How heavy can a pacific Northwest Tree octopus get?

It has no mass and doesn't take up space. It is fictitious.

The "Pacific tree octopus" (pseudo-classification Octopus paxarboria) was a 1998 internet hoax that was intended as a parody of actual ecological awareness groups. Occasionally young or gullible individuals will mistake the site as one promoting the preservation of an actual animal. A small following has provided fake photos, testimonials, and other material.
