>>57015073>>57015080The anime has actually shown that Nihilego has the ability to make these crystals grow. The idea that these could be baby Nihilego actually opens up some interesting implications with some of the other Ultra Space worlds.
Could the tree flowers in Kartana's home world be baby Kartana? Are the muscle man trees in Buzzswole's world giant dead Buzzswole? Craters in Celesteela's world have ventilation tubes sticking out of them that resemble the tubes at the end Celesteela's limbs. Do they have a biological connection to Celesteela? Then there is the matter of the apparently planet sized Xurkitree, whose limbs form some of the pathways in its homework.
Anyone know of anything I may have missed in the other Ultra Beast home worlds that may have a biological connection to the Ultra Beast living there?
