anyone notice how no one ever does hand seals for a kawarimi no jutsu??? i dont get it...i thought you have to make hand seals to perform a technique??? its like...the hokage, when he gets bit by the snake and then all of a sudden he turns to mud...in other eps same things happen...in the beginning during the team 7's survival training naruto attacks kakashi and then all of a sudden it becomes a naruto...! i dont get it
