I'm currently in the Sun dimention in Moon and I really wouldn't know where to go to get themI've got all the tapus but is it really necessary to bring them? And yeah the other 2 UBs are from sun only. I'm not sure if you can switch dimensions and get them from moon however.
I got Guzzlord from the sun dimension, but I heard that it still implements moon's stuff.
And I'm honestly unsure, but I actually am thinking so. I soft reset to try and I couldn't find him at all, but idk!
