What was the name of this kids TV Show?

There was this kids show that I use to watch when I was younger. It had a group of kids that would go into a store, where an old guy would send them to someplace where they had a kangaroo friend the knew karate. His name was Kangarate (If that is how his name was spelled). The intros opening line was something like, "Kangarate, a friend and a teacher too!" At the end of the show when they would come back, they would sing "What you give is what you get" while telling everyone what they learned as a lesson. Does anyone remember the name of this show?
