Is there really a rainbow unicorn octopus?

In the 23rd-25th verses of the Second letter of the Unicorn Frisherello to the Hippocornians, it says "Yeah, verily have we all seen the wondrous glory of the rainbow unicorn octopus, and basked in His grace! Is there one amongst you who can deny this? And did He not say the He will come again amongst us to radiate His benign magnificence upon us, and smite those who have disbelieved in Him?" How can you argue against this?? Who could be so foolish as to risk being smitten by the rainbow unicorn octopus by disbelieving in Him after reading THIS???
