In order to get access to Kanalet Castle in The Legend of Zelda: Link's Awakening, you're going to have to use a series of items with the correct people around Mabe Village. In this Zelda Link's Awakening Kanalet Castle guide, we'll be walking you through using the series of items with the corresponding characters, including a Yoshi Doll, Dog Food, and other items.
Zelda Link's Awakening: How to Unlock Kanalet Castle
A few hours into Link's Awakening, you'll come across Kanalet Castle in the middle of Koholint Island. There's no getting through the main door however, and instead, you'll need to backtrack to Mabe Village, to kick off a sequence of events involving four different items. Below, we've outlined all the corresponding items that you need to trade between characters, in order to gain access to Kanalet Castle.
Link's Awakening Yoshi Doll
First up is the Yoshi Doll. There's a store with a crane game in the southeastern corner of Mabe Village. You need to obtain the Yoshi Doll from this crane game, which costs 10 Rupees per go, and then take it to the north of Mabe Village.
Enter a house with two doorways, and you'll find a mother with a small child in her arms. Speak to the mother, and she'll ask for the Yoshi Doll for her baby. Give her the doll, and she'll give you a ribbon in return.
Link's Awakening Ribbon
With the ribbon in your possession, head out of the house, and downwards. You'll come to the area where BowWow may or may not be chained to a post (depending on your progression in Link's Awakening).
You'll want to enter the small kennel, that's just to the right of the larger house. In here, speak to the small Chain Chomp, and it'll ask you for the ribbon. Hand over the ribbon, and the Chain Chomp will give you some dog food.
Link's Awakening Dog Food
With the dog food, you now need to venture south of Mabe Village, and onto the beach. You're looking for the bright blue shack that's just a small walk away from the shore, where you can find a dinosaur called Sale.
Turns out, Sale loves dog food. Hand him the dog food, and he'll give you some bananas, the final item for this trading puzzle.
Link's Awakening Bananas
You're now going to need to go all the way back to Kanalet Castle. Just east from the castle, on the shore of the moat that runs around the castle, you can find a monkey called Kiki.
Speak to Kiki, and they'll ask you for the bananas. Hand over the bananas to Kiki, and a group of monkeys will appear out of nowhere. They'll all come together and build you a bridge (no, not made of monkeys), over the moat of Kanalet Castle. You've now got access to the castle itself, and this trading puzzle has been completed.
