I have a feeling that senjutsu can only be tought in 1 of the 3 legendary places talked about in Naruto. Mount Myoboku, Ryuuchi Cave, and Shikkotsu Forest. We have seen/know of 2 sage modes from Mount Myoboku and Ryuuchi Cave, but haven't seen a sage mode from Shikkotsu forest. Or have we? (Hint..hint.. Hashirama) Since he welds the power of mokuton(wood element) his sage mode may come from the Shikkotsu Forest. So we may be seeing Slug Sage mode
