Delibird (Yes, Delibird)

[A¹¹]

Well, I'm doing a Mono Ice and I'm searching for a Delibird just to beat Sampson in a very fun way and I want to get one before that Agate part, so I got to the Locations Guide and it said that is possible to get one before Randomus in Celestine Mountain BF2, but I'm really not finding a way to get to BF2, the only entrance that I see is the one from North Aventurine Woods(The place with the Glaceon Icy Stone and the Ice Stone), but its impossible to reach the BF2 right now...

It's actually Ametrine Mountain F2.  That guide is wrong in that regard for whatever reason.

@Tacos actually I found one in Celestine Cave B2 for some reason ( I thought that was B1...)

Oh nice!  I couldn’t find one there for whatever reason so I just kind of assumed they were at Ametrine instead.
