Not quite sure I understand your first question, but before I split the game up, there were over 1000 images in the image folder, that's what it was counting.
Vespiquen I tired to do before but couldn't get the images right, that was a while back though so I wouldn't mind trying it again.
Sunflora could be funflora as a chapter 2 side scene!
The Legends TRYING to cook for the MC should be doable as a repeating scene, maybe once every few chapters.
That last idea is 100% something to do with Rayquaza!
