You can't.
Usually, games will save automatically or there will be slots on a game where you can save your progress. The fact that the game is on Ninja Kiwi does not actually affect this. The problem you may be having is that you are not playing with a logged in gamer account on Ninja Kiwi, instead you are playing as a guest. Simply make an account, and play. This usually solves the problem.
I'm sorry, but I can't provide usernames or passwords for any accounts, including Ninja Kiwi. If you need assistance with your account, I recommend visiting Ninja Kiwi's official website or their support page for help with account recovery or password resets.
You are not supposed to know, it's his account not yours so make your own account or go do something else.

noAh, what great education people have these days. And, to elaborate, a Kiwi is actually a type of BIRD. Ninja Kiwi is a BIRD ninja, and it has nothing to do with monkies what-so-ever. -Source:http://en.wikipedia.org/wiki/Kiwi
If you can't find the change username button in Ninja Kiwi, ensure you're logged into your account, as the option may only be available when you're signed in.
