Get the Deadlyrang first. Then back at HQ, go all the way to your top left. Someone will be there. Jump over to that side and there will be a big red button. Hit it, and it will open up a range where you can test your new Rangs. Inside the range are bags with money. Some you can get only with a particular Rang, but the Deadlyrang is most effective. It can crack through rock, ice, and the metal barriers. After you get the bags, go into the Bunyip Shop just outside the range. Come back out and the money bags will be back. This is an easy way to get money for Rangs.
