Glob World

Glob World is a place first mentioned by Jake in "The New Frontier." He tried to accept his Croak Dream and when his attempt to make it come true failed, he asked "am I in Glob World yet?" meaning that there must be a place where the people of Ooo go to when they die. But there is also the Land of the Dead, which is ruled by Death. In "The New Frontier", Jake says that when he dies, his "individual Earth consciousness is gonna go all over the place while Glob Tallies my deeds." This might mean some people go to the Land of the Dead, and some people go to Glob World. It's confirmed by Pendleton Ward that in a future episode, a "four-headed deity called the Grob Gob Glob Grod will rocket down from Mars to the Land of Ooo. They might be the ones who rule Glob World, and the place might be explained in that episode.
