There's plenty of sensitivity these days around eating octopus (especially since films like Netflix's "My Octopus Teacher" reminded us how intelligent the creatures are.) A new spot from animal rights group PETA and Grey London also wants to remind us not to, but takes a humorous stance to engage our attention.

The idea is that if you eat octopus, you'll fall victim to a curse. So your blood will run blue, your head will turn giant, you'll get googly octopoid eyes and more.  All this is portrayed in a 70s-style PSA format, with some hilarious direction by Jeff Low of Biscuit (who's also behind another supremely comedic ad this week, for Ocean Spray.)

The film ends with the message: "Octopuses are extremely intelligent, sensitive creatures. If you eat them you’re basically a cannibal. Stay human. Don’t eat octopus."

It's running in the U.K. and U.S., raising awareness of a petition to block the development of the first octopus farm in Europe.

“PETA wanted one thing…for people to stop eating octopus. It’s a serious brief that we tackled with a silly answer; by creating a very ‘real’ curse,” said David Wiggleworth, executive creative director at Grey London.
