Getting emoji to look right has for some reason, been a challenge. There was the head scratching over Apple's very plain bagel emoji, while Unicode earlier this year fixed up the once anatomically incorrect lobster emoji.
Although we've seen the lobster and bagel emoji fixed in the past, who knows if Apple will tend to the issue all these years later. But really, do you want to share a squid that's been expelling its own waste over its face? Probably not.
It's no such problem for other tech companies, who have mostly omitted the siphon from their designs.
