How do you get big easy money in Majoras Mask?

To get easy money keep defeating the bird near milk road the one that steals your money if you beat it you can get 200 rupees! However its recomended you use arrows from a safe distance because it will steal your stuff and take it to the curiOSity shop owner. You can beat this birdie as many times as you want.

Also every time you go back in time, the secret 100 rupee treasure chests in clocktown are restocked. You should get them every time you go back in time. You should save money in the bank before every time travel, the money stays there (how? idk) Theres one in the inn in your room and one in anju's room. Also if you climb on top of the roof of the milk bar you'll notice a ledge you can jump off of. if you jump from there to the next ledge and into the baskets displayed at the top of the target shop then jump again to the next ledge theres a 100 rupee chest back behind the octorok game shop. On the third day you can get to 100 rupie chest by going to the vestival tower the construction workers work on using the deku flower! =D
