The Legend of Zelda: Oracle of Ages/Trading Sequence

There is a Trading Sequence in Oracle of Ages, and it is something helpful, although it's a lot of work.

Poe Clock
The Poe Clock is the first item in the Trading Sequence. When Link finishes Spirit's Grave, the first dungeon, they'll see Poe by a rock that can be moved with the Power Bracelet. If Link moves the headstone that is blocking Poe's tomb and Link talks to him, he gives the player the Poe Clock.

Stationary
If the player goes to Lynna Village (Lynna City in the past), and goes to the Post Office there, the postman will give Link the Stationary if Link gives him the Poe Clock. Then the postman will go and run off to deliver his mail.

Stink Bag
In Lynna Village, in the house just below the Post Office, the third item in the Trading Sequence can be obtained. ??? (the hand) is there, and he needs toilet paper. If Link gives him Stationary, then ??? will give him the Stink Bag. Ironically, ??? asked for toilet paper, but he took an envelope.

Tasty Meat
When Link goes to Crescent Island (in the present) a Tokay cook has a bad cold. If the player gives him the Stink Bag, his cold will clear up and he will give Link the Tasty Meat.

Doggie Mask
When Link goes to the the Happy Mask Shop near Lynna City, he needs to give the Happy Mask Salesman the Tasty Meat. In return, he gives Link the Doggie Mask.

Dumbbell
Link must give Mamamu Yan in Lynna City the Doggie Mask so she gives him the Dumbbell.

Cheesy Mustache
Link must go to Symmetry Village (in the past) and give Thomas the Dumbbell, so he will give Link the Cheesy Mustache. Thomas is in the basement of the house in the middle of the village.

Funny Joke
In Lynna City, Link must find the Lynna City Comedian, who will give Link the Funny Joke if Link gives him the Cheesy Mustache.

Touching Book
In Lynna Village, Link can tell the Funny Joke to the sad boy Dekadin. In return for cherring him up, he gives Link the Touching Book.

Magic Oar
To get the Magic Oar, the player must have an encounter with Maple by defeating 30 enemies (15 with the Maple's Ring). Upon encounter, you will drop the Touching Book, and she takes it, but gives you the Magic Oar.

Sea Ukulele
When Link goes to Rafton's house on South Shore near the Black Tower (in the past), Link can give him the Magic Oar for the Sea Ukulele.

Broken Sword
If Link goes inside of a cave near The Coast of No Returns, Link will find the Old Zora. By giving him the Sea Ukulele, he will give Link the Broken Sword, the last item in the Trading Sequence before the reward.

Noble Sword
Link needs to go to Patch, who needs help with his ceremony. By finishing the ceremony, he will fix the Broken Sword and make it the Noble Sword, the final item in the Trading Sequence.
