Possibly but when Naruto summoned Gamabunta they were destroying huge sections of forest.
ok and so what happens when he finds out hashirama is? he see's human body's of chakra, how is he going to dodge wooden spears that are coming to impale him?
He can't .. if hashirama decides to only hold him down, then sure... , but if hashirama decides to take a more offensive method, he'd get killed...
I believe wood release would be able handle gama...
And what you are referring to , i believe happened only in the anime
As to Minato, he would be a pretty terrible ninja if he can't dodge wooden spears. I mean Old Hiruzen was able to block taijutsu hits in the dark from multiple opponents and Minato is faster and has infinitely faster reaction times than Hiruzen.
