Things I'd love from chocobos:

- Breedable birds, so you can get the colour of your choice
- Customisable armour for them, you can see it on the chocobos in the artwork, not that farfetched
- Personal chocobo summonable to you (on a cooldown) that can be ridden and/or used to access storage remotely. (the chocobo in that picture with the guys standing on a cliff is covered in bags)
