I've been having an issue here which involves bouncing back and forth between Rolanberry Red and Abyssal Blue. This has happened three times now and I have no idea how to break the cycle, and go from Rolanberry Red to Midnight Blue in order to bring me closer to Soot Black. I keep hearing RNG is involved, so something tells me I should just keep trying to feed it berries during Rolanberry Red, but I'm stuck in a loop here, so I know if I do so, it's just going to bump me back a step to Abyssal Blue again ><

Any help with this would be much appreciated. My chocobo's level is 7 (since I've heard even your level can make a difference as to how much you need to feed it).
