7th Gen Blue Flabebe/Floette

In Ultra Moon, I have managed to catch 4 of the 5 colors (white, orange, red, yellow) of Flabebe/Floette. Anyone know where to find blue? Thanks.

Please ignore. Sometimes it happens that as soon as I ask a question the next pokemon I encounter is the one I'm looking for. Just caught blue.

Sorry but I'd like to ask a different question about the blue Floette. I've already caught symbiosis red/white/orange/yellow Flabebe/Floette. I spent a bit of time at Poni Meadow to see whether any of the blue Floette would make sos calls (so much so that I got a shiny blue Floette Lol), but no calls were made. Can anyone help me by letting me know where blue symbiosis (HA) Flabebe/Floette can be found in Ultra Moon? Thanks!

Cannot catch a blue Flabebe with its Hidden Ability in Generation 7.

Suggests trying the Global Trading System. Was possible to find through X/Y's Friend Safari, apparently. May have transferred one to Sun/Moon.

Thanks for the reply/info!

Yes, they can be found in the Friend Safari. I was fortunate enough to get into someone's FS that had a blue symbiosis Floette in X. The Friend Safaris are definitely the easiest way to get HA mons. Just a couple days found some nice HA pokemon like infiltrator Lampent (who will make my starter team when I start Alpha Sapphire soon), Gogoat, Ocean Vivillon, Gabite, Shelgon, Fraxure, Spritzee, Swirlix, etc.
