Juugo likes friends! He's a little shy around people still, but he'll warmly welcome positive responses to him.

He acts a little like a bird though, so Masa might pick that up. (Kid was essentially raised by birds okay)

Of course, now we have to figure out how they'll meet. Juugo might be rushing to Konoha during the bodyswitch in order to cuddle with Nagato. In Ami's body. So that could be interesting, hmm
