First-floor mobs recycled and buffed to be level-appropriate in the expanded map, fought by Imani's team.
Imani's team clashed with chilly goats while operating in the new area tacked onto the battlefield when the The AI enlarged the playing field. Chilly goats were mobs from the very first floor, and their reappearance is Carl's evidence for how the expanded map works: there is no rhyme or reason or quests, much like the first floor, because the AI is recycling mobs from all previous floors, changing them up a bit and strengthening them to be level appropriate.
They sit alongside the Danger Dingo-Riding Kobolds that Jurgen's group fought and the Rolling Battle Formation Ball Carl hunts as examples of the same recycling.
Recycled first-floor mobs, an example of the AI's mob-reuse in the expanded battlefield.
