>>26805011That second NPC gives you the totem poll item thingy. It was just a tease that the next Region would be Hawaii inspired, is all.
Seriously went over peoples heads though, people still speculate about that "mystery" to this day.
As for the first one, I don't know, but seeing as Mega Stones came from space, I will guess that this NPC is wrong, and that it's just a big space rock. Not the only NPC in X/Y that feeds you misinformation about Mega Evolution. One NPC speculates that Mega-Aerodactyl is it's "Primal" form from before its fossilization. However "Primal" forms became an actual thing in OR/AS, and did not include Aerodactyl. Was possibly just teasing the concept of Primal reversion, but the NPC himself was definitely incorrect.
