The Lumpy Abyss is located in Lumpy Space. Lumpy Space Princess stated you have to travel in floating cars in Lumpy Space or else you will fall in the Lumpy Abyss. The Abyss could be never ending, or end in a Black Hole.


  • It may be so in "The Other Tarts" that the Royal Tart Toter may have drifted in the Lumpy Abyss, since he spun into another never-ending portal with Lumpy Space Princess also being there.
  • Abysses usually have an ending, but LSP stated that's it's a never ending fall into Lumpy Space.
