The martians resemble green blobs, and the part of their bodies that attach to the ground is light green. On top of their heads, they have a blue, curled antenna, along with multiple blue spots, and they have yellow eyes with red pupils. They also have two arms, pink tongues, and teeth. They seem to like Krabby Patties.
When Squidward is sent to Mars to deliver food, he encounters three martians. He says that he has a delivery from the Krusty Krab, causing one of the martians to grab the bag, pull out a Krabby Patty, and eat it, commenting that it is "yummy, yummy."
Squidward, looking around, then comments that "this dump needs a true artist touch," angering a martian and making them eat Squidward alive. The martians then fly a spaceship back to the Krusty Krab to return Squidward who was covered in goo.
