Holy, fucking stupid crap.

I can't believe how well they made the sprite, the colors and tones picked for her are exactly the ones you would see in the SNES era for sprites.

There's a very good reason for that, along with the general talented nature of the rest of the animators one of the main people who worked on this episode is Paul Robertson a professional sprite artist. He also worked on the earlier episode "Fight Fighter"
