Keen Republic

The Keen Republic started out as a blank white place that Thomas rescued Runnervous from in Chapter 1 Part 13. It was taken over by mutated rats who stole human DNA and formed it into a Bikini Bottom rival city. It was known for actually having edible chum, which inspired Shelby to turn them into chum. This caused Food War V, but it eventually became a kingdom of the Sealand Empire, which was eventually dissolved-along with Keen-by SpongeKirby. It contained a huge Pizza statue of Shelby after he helped them gain independence.
