Creating Dynamic Pixel Animations from Static Poses

First, use niji 7 to generate a pixel-art game character:
pixel art of an anime girl knight in blue and white armor, with pink hair, holding a sword and shield, in the style of pixel art. --ar 1:1 --niji 7

Next, use Nano Banana to create 9 different poses of the same character:
Generate a 3x3 grid on a pure white background, showing 9 different side-view poses of the same character.

Finally, use Grok to turn the 3x3 sheet into an animated sequence:
This is a 3x3 character sprite sheet containing 9 different poses of the same pixel-art character. Make each character move with subtle motion like an idle animation in a pixel game. Each frame should have slightly different movement rhythm and details, creating an overall GIF-like animated feel.
