How do I get The Keaton Mask.I know he's a ghost but I don't know where..

You get the Keaton mask when you go through the process of getting the postmans mask.

Hope I helped<( " )>

This takes a while..To get the keaton mask first you have to have the mask you get from the mayors wife,the one that looks like her missing son.I forgot the name.(lets call it kasuf )Between 10 and 4 ( forgot exact time sry) of the first day the postman will visit the inn, in clock town. Put on the kasuf mask and talk to the lady behind the counter after the postman gives her a letter.She will ask you to meet her later that night at midnight.Use the orcarina to go forward to evening of that day. Make time go at regular pace so you don't have to wait as long.You will need to turn into a deku scrub and use the flower next to the inn to get in from the top floor after it closes.
Go in the kitchen and wait till she comes down. When she stops talk to her and she will give you a letter.Go directly to a postbox and put the letter in .Fast foward to dawn of the 2nd day.Go to the landry pond on the east side of town.(You have to go up a ramp to get to it.) Wait untill a boy comes out and meets with the postman.Then when the boy goes back in the house, folo him .The door will now be unlocked.Go up the stairs and talk to kasuf to find that the skull kid turned him into a boy.He will give you a pendant. Go and give it to the inn keeper. She will say stuff...blah blah blah blah blah.Use the orcania to skip time till the dawn of the 3rd day .go back to the landry and talk to the the guty upstairs in the house he will give you the keaton mask....if you can't get in go to the evening of the 3rd day.If you need more help I know how to get all the masks.

*This process is just a tad long, just to let you know. Talk to Anju at the Stock Pot Inn between 1:30 and 3:30 on the first day to get the room key. *If you don't want to get/ can't get the room key, then you can get into the Inn late at night with your Deku Scrub Mask and fly to the top of the Stock Pot Inn and go through the door. Then, talk to her again, but with the Kafei's mask on that you got from Aroma in the Mayor's Office. She'll tell you to meet her again in the kitchen late at night. When you go to meet her, she will give you a letter to Kafei. Post it and wait until day time. When the Post Man does his rounds and picks it up, then you can follow him around until it is time for him to deliver it. Follow him back to Kafei's place as he delivers the letter. When he rings the bell at the Laundry Pool, Kafei will run out to get the letter, and now you have to hurry up and sneak into his hideout, you sneak. ;^) He will give you a memorial pendant. Take that to Anju. After that, hang around until 1 pm on the third day and go to Kafei's hideout. If you didn't stop the burglar on the first night, then go inside the hideout and you will find the curiosity shop owner. He will give you the Keaton Mask.

If he is a ghost you mean the Kamaro Mask (Ithink thats how it's spelled). To get that mask go to the mountain entrance and check the mushroom shaped rocks until you see some guy dancing. Talk to the ghost then play the Song of Healing. Then you get Kamaro Mask.
