As we all know Jiraiya fall to the deaps of the ocean during the battle with Pain. And the toads traveled across the ocean to konoha to break the bad news. Also Kabuto said it was deep in an ocean.
But there's no water near the hidden rain village its in a land contienent.
Take a look at this map, the hidden rain village is the symbol with 4 vertical lines.
So what water did jiraiya submerge in?
What water did the toad travel accross to break the news to Konoha?
I understand you can have water bodies without being near oceans but that implies Lakes and rivers. But lakes and rivers(rivers lead to the oceans) arent deep to the point you cant go to the bottom and retrieve a body like Kabuto wanted to do.
Hate to say it this actually maybe a plot hole seems kishi has changed the narutoverse landscape without showing us an upto date version lol.
