I'm curious about these other 2 summons, maybe they are just again, children of Katsayu and Manda. Really is good to see more than just one slug and snake summon for once, I mean we focused for so long on the frogs. Its about time we saw the other 2. I don't think this means we would see a slug sage mode but many of us were hoping Sakura had something like it so it would kinda complete the set and there would be at least one female sage in the series. Otherwise though things are fine. Most still suspect the humid bone forest to be the residence of the slugs.
About Gamachicki giving the girlfriend comment, its possible last we saw him, he was with Sakura and Tsunade when the village was in ruins after pain attacked. He did see Sakura hug Naruto so he may crack something at him like, "Oh Naruto I see your girlfriend is here too." only for Sakura to yell or Naruto telling him to stop out of fearing Sakura's strength. Would be another short funny moment. All I am expecting from this scene is a situation like when the Sannin fought, but all working together along with the animals.
I can see Gamachiki using a toad oil technique or possibly an air one, Sakura's slug may use an acid technique like Katsuyu, no idea aside from poison on Sasuke's snake.
