I read the manga where in this scene Jiraya says that he believes it was Uchiha Madara summoned the 9-tails and led it to attack Konoha. But if that's true then why are there 8 other beasts with tails? Did Madara summon them too or was there an organization that each created these beasts? Help anyone?

ok, all the summons are actually in the world somewhere, when you summon it, you just teleport it to where you are. so the 9 tails, and all the other beasts are already somewhere in the world, so madara just teleported the 9 tails to konoha for some reason. my guess woul dbe to get rid of the 4th.
