kabuto says "Shikkotsu Forest" is equally famous as "Mount Myōboku" and "Ryūchi Cave"
and we know Mount Myōboku = location to learn frog sage mode and Ryūchi Cave = location to learn snake sage mode
^^^^^ if these two place are for snakes and frogs, then LOGICALLY, "Shikkotsu Forest" is for slugs, right???
Will Tsunade or Sakura learn slugs sage mode??? (if im right about Shikkotsu Forest being the location to learn slug sage mode )
