The Squid Doodle was a picture drawn by Patrick in the episode "Frankendoodle." He also appears in various video games.
The Squid Doodle resembles a jellyfish, but with Squidward's face. Being a drawing, it has a 2-D appearance that is black and white.
Role in series
When Patrick draws it on the ground, SpongeBob thinks it is another jellyfish, as he drew one earlier, but Patrick says that it is Squidward. It soon comes to life, shaking its fist and yelling in gibberish. It is soon erased by Patrick because they cannot allow it to roam around town.
