In naruto Shippuden Kankuro does get hurt really badly by Sasori but Sakura heals him and then he is back to normal (woo!) :D
Yes, Kankuro can eat.
The one on kankuro's back is ''Crow''. The One he summons to trap his opponets with a buck head shape is the "Black Ant". The One that protects him and shots fire in Shippudden is called Salamander.
No he doesn't
Temari is Kankuro's sister he's supposed too
Dress up as Kankuro and convince a friend to be a puppet
sasuke is way stronger than kankuro
Naruto and the others (Team 7: Sakura, Kakashi, and Chiyo/ Team Guy: Neji, Lee, and TenTen) save Gaara back. Chiyo uses her remaining chakra (and life force) brings Gaara back to life. Kankuro also recovers at the end.
Sasori is technically dead so it's fine to use him as Kankuro's puppet. He's the master puppeteer but ironically turned out to be someone's puppet in the end. I was shocked too. His legacy lives on!!!
Kankuro
temari
Yes.
