Chocobos have changed, and Moogles have changed.

Chocobos have come in all sorts of colors, there's been breeding, hot and cold minigames, stables to rent them, and just random places to catch one. While the design may not have changed, it still has changed. Moogles are in a similar way. In FFVI for instance you get one on your team.

Cid works in a similar fashion. He typically has something to do with airships, but not always(aka FFVI). Either way he is almost always related to technology of some sort.
