Jiraiya has a queue of like, 3 different things that he sent back to Konoha.

It's interesting....but I can't think of a single time where a good guy's summon has ever been attacked by a human villain. They just....left pa there, even though he previously demonstrated relatively formidable power against them. Conversely, Oro's lost 3 snakes to Jiraiya and Sasuke, then Manda got stabbed in the mouth by Tsunade and then blasted by Deidara.
