Answer 1

bao

Answer 2

Kadang-kadang is a game wherein the players would have a coconut shell which is well polished; the brown one, they tie a string to it then they would balance themselves onto the shell and walk with it to the finish line--endurance, equilibrium is needed.

Another one which I have heard of is the bamboo. If you watched Kung-Fu Panda you would know this; they make a foot supporter attaching it to the bamboo and you are to balance yourself onto that and while holding the body of the bamboo. This is quite difficult than the coconut shell thing.
