Cookoroni is the third episode of Mixels. It shows all the tribes of the first wave and them bickering over their last Cookoroni. It's definitely the most max filled episode in these earlier episodes. It does show more of the Mixels world by showing another snack, the Cookoroni, and shows all 3 members of all 3 wave 1 Mixels, showing how they interact with each other. It takes place in a similar area to the first episode, Coconapple, so it can't really be said it explores another part of the world at large. The conflict in the episode is very much the Mixels fighting each other and they're all on the "good guy" side for the entirety of the series, so this episode isn't necessarily good vs. Evil but more like good vs. Evil. It's kinda like civil war from Marvel comics, with both sides having the good guys, but this episode has the 9 characters fighting each other, shorting themselves into 3 teams when they max.
Overall, this is my favorite one between the first 3 episodes.
