It does sort of resemble this image, though the sprite is still pretty generic. I don't remember if this was just a common NPC sprite, but I wouldn't be surprised if it was. Keep in mind she wasn't playable in the SNES version, so she wouldn't need a unique sprite.
The scene is from a Courage episodewhere a Fish appears and in the LatAm Spanish dub, speaks with a heavy Argentinian accent and even refers to legendary Argentina soccer player Maradona.
