If you could summon an animal from the three sannin...

Frog because they have more mobility and they can perform fire and water jutsu.

I'd would not like to summon any of em cux they r fugly, but when id realllly had ot choose then frog.

definitely frog

i would go for both the snake and frog, look how the older sasuke uses the snakes in combat and cause i like the frogs too

hmmm....not the slug cause its prob not a good idea to have a summon who's weakness is a pinch of salt...oh noes dont cry on the slug!

not the snake cause he looks mean

not the frog cause frogs are gross...

so i pick... none..cause they all suck...ill find my own summon thank you

snakes of course....bad ass snakes

Manda!!

i like manda the big snake

Snake...ssshhhhHHHH

I'd go for the snake. I'm assuming that, just like Jiraiya, there are actually a bunch of different snakes that Orochimaru could summon, but we've only seen him do the super huge one.

Orochimaru is my favorite character and his whole mantra is that being the best ninja means you know every jutsu and make your own insane level jutsu. Because of that, I feel like if he chose the snake then he did it because its got some insane abilities.

MANDA the snake........ i love snakes

Manda.

He can kill all.

I think they're all awesome in their own way, but I would choose Manda, just because I like snakes more xD

slug...i would kill a frog without even trying! (petting it too much that its pores clog and it suffocates)
if i could summon an animal it would be an elephant.

frog or slug for its healing abilities
