A Quokka Dreeds its Weird

Someone refresh my memory, since it's been so long since I read the volumes where he was introduced: What exactly does Orochimaru want? Do we know what he has against Konoha? Also, is he one of the legendary three ninjas, along with Jiraiya and Tsunade, or is Kakashi the third?

When the chuunin exams devolved into "OMG! Orochimaru and his resurrected and non-resurrected ninjas are attacking Konoha! Everyone run to defend it!" I expected there to be a massive battle involving everyone we've met so far, but that... didn't happen. I was a little disappointed. Also, I was not terribly invested in the Third Hokage, so his death didn't have a big impact on me. (The flashback to Kid! Iruka crying over the grave of his parents did.) Loved the flashbacks to Jiraiya and his crew as baby ninjas, though.

I was very pleased with the introduction of Tsunade, since this manga needs more kick-ass kunoichi, and that she became the Fifth Hokage. As for her giant slug... that was very strange. As was the most bizarre jutsu yet, Jiraiya teleporting people into the esophagus of his giant frog. Ew.

All the same, much as I like Naruto, Jiraiya, and Tsunade, I missed the rest of the old crew in this arc. I'm hoping the next arc will get back to them.

No sign yet of Gaara or the other Sand Village ninjas.

Jiraiya is a much better teacher than Kakashi.

Finally, if I had Uchiha Itachi as an older brother, I would probably have a chip on my shoulder too.
