Also I call bs about the "deeps of the sea" crap Kabuto spouted off to Madara because its true regular snakes aren't adept to diving but we clearly saw Manda II's proficiency with underwater. It fricken made that Squid its bitch in it's own underwater element and Kabuto even said since Manda II is a genetic freak its 10x stronger than the regular Manda. Once again Yazen ask yourself, If Kabuto was about to get the body/DNA of people like Nagato, Itachi and fricken Deidara (who was disintegrated off the face of this Universe and not even Jesus Christ himself would find a scrape of him left) you really thing water would stop this guy?? If there was a will Kabuto would find a way.
The only thing I could agree with you about is the fact that I too agree that Jiraiya isn't really worth lying about. Compared to the other zombies he has Jiraiya is just 1 badass zombie fodder that he does not have under his thumb.... however Jiraiya was apparently strong enough for to even be mentioned so who knows. Again, not saying that we will see Jiraiya but that half ass excuse Kabuto gave Madara was just stupid to me and I can see so many ways around that.
