Mass Sprite Sheet Expansion Battle & NPC

I've seen it, read it, poked it with a stick, moved it around and made it longer.

Still couldn't tell you a single thing about it though. Seem to think every time I've followed a lead on a free palette, it always turned up a dead end. That being said, if a standard palette can be sorted and reordered, why not two palettes sorted and reordered into one 12 color palette?

Way beyond my ability though.
