(ACAFE - 2021)

Text 2

When it comes to looking inedible the squid
goes all out. Tentacles, suckers, big blobby eyes,
anything to help communicate the message
"Do not eat me, under any circumstances".
There's even a beak in there somewhere.
It's really more threat than feast.

Which got us thinking. What on earth
was the first person to eat squid doing?
Who in their right mind could look at
raw squid and say, "That's the snack for me"?!?

TO THE VISIONARY WHO FIRST SAW
¹TENTACLED BRAIN SACS
AND THOUGHT "LUNCH".

What a weirdo. What a hero.
Because as we know, squid just happens
to be one of life's greatest pleasures:
chargrilled squid salad, chilli squid linguine,
crisp calamari dunked in mayo...

So we'd like to say a heartfelt
thank you to the first person to eat squid.
And to all the food pioneers who boldly
ate what none had eaten before -
giving those funny-looking foods
the chance to be delicious.

Text 2 above is one of Hellmann's (the food brand) awarded advertisements. What does the phrase "Tentacled Brain Sacs" in ref. 1 refer to in the ad?
