Sometimes a Chicobo can be a different color than its parents due to the Chocobo mutation chain, which can be read about in the Chocopedia. This mutation happens when you give two Chocobos Loverly Gysahls, (20% chance of mutation) or Golden Gysahls (50% chance). As Chocobos go down the mutation chain, they gain better abilities.
To instantly grow a Chicobo to an adult feed it a Gysahl Cake.
To get a Chicobo to consume a Gysahl Cake, one must first tame the Chicobo as all Chicobos are wild and untamed. Otherwise, it will not accept the Gysahl Cake.
Naming the Chicobo and making the Chicobo follow, wander, or stay requires a Chocopedia.
To make the name visible:
- Right-click (or the default "Use Item" key) on the Chicobo or Chocobo with a Chocopedia; this will open an Interface.
- If you do not like the current Name, enter a new one (Click the rename button).
- Click "Name Hidden" to change it to "Name Shown".
- Click "Confirm" to finalize
