Four kingdoms

The Four Kingdoms reside on the other side of the Imaginary Universe in Problem Sleuth. It appears to be a complex land involving four different creatures that all have unstoppable desires to do something that the other creatures dislike. This is known as The Plight of the Four Kingdoms and is part of the Weird puzzle shit that the entire story goes through as Problem Sleuth, Ace Dick, Pickle Inspector, and Mobster Kingpin must complete their Quest of Spirit to gain a boon. The four kingdoms have Weasels, Elves, Hogs, and Clowns. Each Kingdom does something irrevocable to another Kingdom, causing much political strife that Problem Sleuth is eventually made to address. When Problem Sleuth completes his divine mission through cheating, he creates a Treaty and gives it to the Weasel King to see through Adobe Treaty-Viewer.

Now that the Four Kingdoms are united, Problem Sleuth can use the boon granted to him to summon the Four Warriors to assist in the battle against DMK.
