The four are often evoked as religious entities in the Land of Ooo, as Jake is shown to believe in "Glob World," and Finn at one point speculates Candy Kingdom people worship Glob in church.
Glob, Gob, and Grod were mentioned in episodes before the full nature of "Grob Gob Glob Grod" was revealed:
- "Trouble in Lumpy Space": Lumpy Space Princess is known for frequently shouting the phrase, "Oh my Glob!" She first does so when Melissa reminded her about the weekly Promcoming Dance.
- "Mortal Recoil": Jake is shown saying, "Oh my Gob, oh my Gob, oh my Gob!" after he's frightened by the Lich in Princess Bubblegum's body.
- "No One Can Hear You": Finn asks, "Are y'all at church, worshiping Glob?" while he explores the suddenly deserted Candy Kingdom.
- "The New Frontier": Jake says that his "individual earth consciousness is gonna go all over everywhere while Glob tallies my deeds" when he dies, a phenomenon which he refers to as "transcending into Glob World." Also, Jake says "Oh my Grosh" before telling Finn about his Croak Dream.
- "Web Weirdos": when Ed asked, "Tell me, Glob... why don't you ever answer me?!" when he was trying to fix his relationship with Barb. At the end of the episode, Jake tells Finn, "Go with Glob," before he goes to help Ed.
- "I Remember You": Ice King says, "Grod in the sky, please tell me why!" Ice King also starts to apologize to Gob in "Bad Little Boy" for not believing in him when Marceline starts messing with Ice King.
- "You Made Me": Lemongrab, screaming to Princess Bubblegum, "You made me! You made me! You're... my... Glob! You're my Glob!"
- "Burning Low": Princess Bubblegum looking at her diary and saying, "Oh Gob, I thought I would be ready for this." And after Finn got a burn on his foot, he ran to the water, saying, "Oh Gob!" three times.
- "Bad Little Boy": Marshall Lee says "Glob" when Fionna finds out that he was faking his death.
- "Frost & Fire": Princess Bubblegum says, "Ach, mein Glob!" ("Oh, my Glob!" in German) when she sees Flame Princess and Ice King hurtling together in mid-air.
Grob Gob Glob Grod have some form of telekinesis as they were shown lifting Jake as the Magic Man off the ground without touching him. They can also levitate, as well as being able to drain Magic Man's powers. Not only are they able to survive and even talk in the vacuum of space, but they are also capable of flying extremely swiftly, being able to reach Earth from Mars in a matter of minutes. They can also somehow track down people, as shown in the beginning of "Sons of Mars" when one of them was tracking down Magic Man. Grod is also said to be a very good drawer.
Grob Gob Glob Grod is a roughly humanoid shaped being. They have four faces, one on each side of their head. The faces can sometimes all talk at once. They are also bald due to Magic Man casting a spell on them. Their head appears to be floating and not actually attached to their body. The red, jewel shaped part on their head is not part of their body, but a piece of headgear that conceals the baldness caused by Magic Man. The shape of their eyes vary from having dots for eyes to having fully drawn eyes during close ups. They have a sword that has a white spiky core that emanates a blue aura.
Grob Gob Glob Grod are the older siblings of Magic Man. They banished Magic Man to Earth 200 years before "Sons of Mars" for several crimes against the Martians. In "Sons of Mars," they brought Jake (whom they thought was Magic Man) to Mars for trial. Although they express enmity towards Magic Man, they still respect him as a brother; this is shown when Finn and Jake offer to go after Magic Man and Grob Gob Glob Grod tell them "I don't want to lose my brother."
Abraham Lincoln and Grob Gob Glob Grod both lived on Mars. They seemed to be good friends, as Grob Gob Glob Grod are saddened and say that they have lost a friend when Lincoln died in "Sons of Mars" after offering Death his immortality in exchange for bringing Jake back to life.
Grob Gob Glob Grod were apparently good friends with Prismo, as they were seen at a party in his Time Room in "Wake Up." They unsuccessfully hit on a Water Nymph named Denise, but put her off by asking if she could date the different heads on different days of the week. Later, they took cell phone photos of themselves with the catatonic form of the Lich.
- Before the episode "Sons of Mars" aired, Pendleton Ward said Grob Gob Glob Grod would appear in an upcoming episode and rocket down to the Land of Ooo from Mars.
- After Finn dies in "Puhoy," he comes across a being resembling Grob Gob Glob Grod.
- In "Astral Plane," he is referred to as "Gob Glob Grod Grob" instead of "Grob Gob Glob Grod"
- Grob Gob Glob Grod's multiple faces are similar to the Indian god Brahma, as well as the Buddhist deity Asura and the four-faced angels described in the Biblical Book of Ezekiel.
- Additionally, their pointed head shape and body design also draw similarities to the Flatwoods monster.
- Additionally, Ward originally wished to cast the heads of Grob Gob Glob Grod as Bill Murray, Bill Cosby, Bill Clinton, and Bill Nye the Science Guy; however, this did not happen.
