While the Kyuubi was getting a bath that was turning into a drowning compliments of one of Senju Tobirama's Water Jutsu and one Senju Hashirama's Mokuton, Namikaze Minato came back and decided to help his predecessor pull Orochimaru's arms away from his neck.
While being strangled couldn't kill the Sandaime because he was already dead, it was highly unpleasant. With Minato's efforts and a Kunai, the third and fourth Hokages managed to pry Orochimaru's arms away. They fled as soon as they did so.
"Well, that's creepy." Minato said as the arms scuttled off into the distance to regroup.
Sarutobi Hiruzen said nothing as he was busy taking in several lungfuls of "air" and rubbing his sore neck which had been stabbed a couple of times in the scuffle between the Yondaime, himself, and Orochimaru's arms.
"So, are you guys going to help, or are you going to just sit there?" Hashirama called down from where he was dunking the Kyuubi.
The Sandaime and the Yondaime turned to look at each-other before moving to join Hashirama and his brother in their attempts at drowning the Kyuubi.
"It's good to see you again." the Sandaime said.
"You too." the Yondaime replied.
