The magazine has a light yellow background. On the front cover, it says "Squid Ink" in purplish-blue writing, and underneath the writing, there is a blob of ink shooting out of a pen.
Role in episode
Squidward can be seen reading it when SpongeBob wants to eat a Krabby Patty with Patrick in the Krusty Krab. It actually looks more like a comic book than a magazine, since it looks like it has only four pages. It could also be a magazine like Teen Ink, except for squids.
