Apologies, I didn't notice this. xD
After spending a significant amount of time with the giant bat, I was ready to return. I was getting myself used to flying and it was a good feeling. Upon landing, I get off the giant bat and have to it goodbye before it disperses. I then go to you and after receiving instructions from you, I look around the cave and notice the bats hanging upside down from the ceiling. I then proceed to try out the technique. I close my eyes while making the horse hand-seal and focus my chakra. I focus on the bats before releasing my chakra in the form of ultrasonic waves. My chakra would come in contact with them and I test to see if they respond to my "call". Try this for days until I can separate my echoes from my calls and then spend some more time making longer calls and separating pulse and echo in frequency. I keep practicing until I master it and keep in mind of the range bats use to avoid deafening. Once I was ready, I return to you with some bats moving with me.
"Hmm it is great...But what should I have them do?"
