I'm glad that other teams got some of their spotlight... Except for poor Lee and Ten-ten. But yeah, I guess Sasuke could still summon snakes alongside birds then? That confused me slightly. And when did Gamakichi get big enough to cause a scene?
And did anyone else find the gag on page 20 hilarious?
Yeah, that confused me a bit. I was always under the impression that you can only have 1 summoning contract at a time, and the only reason why Sasuke got hawks was because Manda was dead and so he was free to sign another contract. But if he can still summon snakes, it could either mean that he gave up hawks to summon snakes again, or you really can have multiple contracts but just can summon them simultaneously (unless you have a Rin'negan). Hurray for ambiguities that will never be solved or expanded upon!
If it is just summon the two animals but at different times, I would imagine that the animal you attempt to sign a contract with may have issues with you having multiple contracts. Kind of similar to how different masters of stuff (like martial arts, japanese drumming, etc.) may get offended if you ask to become their student when you already have trained with other masters.
But then again, Sasuke is the only one (besides Pein) shown to ever summon more than one type of animal and Kishimoto has an uber boner for him sooooooo
