The Pup Kingdom is a state in the future Land of Ooo built by the Pups. It is likely ruled by Gibbon, and formerly by Beth, who is now a fugitive. Based on their appearance, it is heavily implied that the inhabitants of the Pup Kingdom are descendants of Jake and Lady Rainicorn.
- The Pup Kingdom first appeared in promo art for "Graybles 1000+," though it was never seen in the actual episode.
- The Pup Kingdom is shown thriving during the intro of "Come Along With Me".
- The Pup Kingdom looks similar to the Jake city seen in, "Everything's Jake".
