GOLB is a huge red statue with four giant eyes. It has a great purple tongue and pronounced teeth and gums. Its head is made of two geometric shapes: a cube topped by a pyramid. It is surrounded by green cubes in the middle of nowhere.
- GOLB's name has not been stated in the show. It was revealed by Adam Muto on Spring.
- It loosely resembles the Frederator logo.
- GOLB's backside appears in promotional art for "Astral Plane".
- GOLB has a number of blocks floating around it that look similar to those seen at the end of "The Lich" and "Finn the Human."
- The shape of its head, its color, and its name is similar to Grob Gob Glob Grod from the episode "Sons of Mars." This may mean they have a connection with each other.
