^she didnt want to get her dress wet
ot:similiar but different. she controls each ones unique trait as her power. i wonder if she made them or they came with her sharinegan?
I got the idea they were all different planets, a planet with a surface of mainly stone and lava, a frozen planet, a planet with strange metal geography and high gravity, a planet in the center of the universe named the "genesis dimension" because it's where everything came from. The last one is definitely stretching it though.
But maybe the ice block she transported Naruto and Sasuke into was made from frozen moisture in the air rather than spawned from nothing, and she couldn't do the same trick with lava or acid because she'd need to actually be in the dimension and lift up the substance through her abilities which would take more time.
