Ok, this is very frustrating for some people. I know it was for me. I had to look an numerous FAQ's to get it right...but sometimes the people that write them seem to leave out minor details that is done wrong, will make you have to start all over again! So here's my guide, as I did it, which worked very well.
Dawn of the First day:
Tip:Keep time noraml flow for right now, there's a lot of waiting involved and if times going slower, you'll have to wait longer.
Wait around till about 1 PM then head over to the stock pot inn.
At 2pm the post man will come in and hand Amju a letter. After he leaves talk to anju wearing the Cafe mask ( the one that looks like a kid with purple hair)
you get this mask from the mayors wife. She's in the mayor's office...talk to her, and she'll give you the mask.
Anju will tell you to meet her at 11:30 in the kitchen. You can now skip to night of the first day.
Night of the First Day:
Ok now, put on your deku mask and hop into the flower outside the inn.
Land on the straw roof...wait till a little before 11 pm to go in tough. Because if you go in too early it will close and kick you out.
Go to the kitchen and wait for anju. notice the bugs on the floor (EWWW I wouldn't want to stay there)
Talk to anju and agree to help her. she'll give you a letter.
mail the letter outside in the mailbox. Skip to the next day
Dawn of the Second Day:
Wait.................................................................. ................................................................................. ...................................wait......................................... ............................ .............look at your shoes..........................................wait................................................
At around 2 pm go to the laundry pool. It's the little room with the stream and and the bell that summons that shy kid.
wait for the mailman to deliver the letter.
Run to the door that's now unlocked and run up the stairs and talk to cafe.
Get the pendant from him
Go back to anju and give her the pendant. Skip to the finale day.
Dawn of the Finale Day:
Now some more waiting................................................. ...............................................
At 1pm go back to cafe's little room. The wierd guy that scrathes himself will be their. He'll talk awile, and give you a mask and a prioty mail.
Play the inverted song of time to go slower. Skip to night of the finale day.
Night of the Finale Day:
Tip: The next few things have to be done as quickly as posible of you will run out of time.
Go to the milk bar and talk to the mayor's wife wearing the cafe mask.
Give her the letter and then she'll give you a bottle filled with Romani milk
Tip: Romani milk will give you unlimited magic until you play the song of time. It is VERY expensive (200 rupees). It would be a wast to use it now when your on the last day and won't even be useing any magic power anyway. But since the milk will disapier when you go back in time, after your done sell it in the curiosty shop for 200 rupees then put the money in the bank.
Now warp to Ikana canoyn and put on the bunny mask. Jump into the water and swin to shore.
PUT ON THE STONE MASK! If you don't Sakon will see you and you will have to do this all over again!
Run twords the side of the river. You will go through a tunnel and when you come out you will be in front of Sakon's hideout.
You MUST get here by 7PM.
There is a stone piller towards the wall, behind it is where you'll find Cafe.
Take off your mask and talk to cafe.
wait BEHIND THE TallER PART OF THE STONE. If you don't sakon will see you, and you'll have to do it over again.
At 7pm sakon will open the door and cafe will run in. Run in after him.
There will be a short cut seen of cafe stepping on a blue switch...making his mask go on a convyer belt heading towards a hole.
When you get control again step on the blue switch.
You will now have control of cafe
Run into the room and step on the blue switch. Red switches will speed up the convyer belt so DON'T STEP ON THEM!
It's ok to step on yellow switches, they slow down the belt.
When you see blocks you can only push them in the direction the picture is on.
When you become link run into the room, and kill the enemies.
Tip: It helps to have the fairy or gilded sword.
When you get to the finale room step on the blue swuitch as cafe. Then as link.
Cafe will get his mask, and run away. warp to clock town and go to the inn.
Go to the room that said Empoyees only. It is on the second floor. Wait (it'll take awihle) till cafe comes, and watch the scene. Then you'll get the couples mask, and Most importantly...You'll have helped anju and cafe!
