Quick answer · Switch 2 remake
How to Get the Biggoron Sword
You get the Biggoron Sword by finishing the adult trading sequence: start with the Pocket Egg from the Cucco Lady in Kakariko, trade your way to the Broken Goron’s Sword, take Biggoron his eye drops, then show him the Claim Check after three days.
The chain runs through Kakariko, the Lost Woods, Gerudo Valley, Death Mountain, Zora’s Domain and Lake Hylia. Three deliveries are on a countdown and cannot be shortcut with warp songs, so get Epona first. The reward is a two-handed blade that hits as hard as the Giant’s Knife but never breaks.
What changed in the remake
- Confirmed The Odd Mushroom delivery timer is four minutes on Switch 2, up from three on N64. One other remake guide still lists three minutes.
- Single source One remake guide lists shorter windows for the last two deliveries: two and a half minutes for the Eyeball Frog and three and a half for the Eye Drops. Another remake guide gives the N64 values of three and four minutes.
- Single source The quest appears in the remake under the name “From a Pocket Egg Comes…”, and some trade item names were changed.
Before you start
This is an adult-only side quest, and it is long. You will want Epona for the timed runs across Hyrule Field, a bottle of Blue Fire from the Ice Cavern to thaw King Zora, and the Sun’s Song to skip the final waiting period. A way across the broken Gerudo Valley bridge is also required: either jump it on Epona or use the Longshot from the Water Temple.
The best time to finish the chain is after the Ice Cavern, because the King Zora step cannot be done until you can carry Blue Fire. You can start earlier and park the chain at the Prescription, since only three of the trades are timed.
Delivery timers: what the remake guides say
Remake sources do not fully agree on the countdowns, so plan for the shortest numbers. VGC and games.gg both put the Odd Mushroom at four minutes on Switch 2, while FinalBoss lists three. For the Eyeball Frog, games.gg says two and a half minutes and FinalBoss says three. For the Eye Drops, games.gg says three and a half and FinalBoss says four. If you ride efficiently on Epona and avoid detours, any of these windows is achievable.
Every source agrees that warping with an ocarina song during a timed trade spoils the item, and you then have to go back to whoever gave it to you and start that link again. Sources also disagree on whether the Odd Potion is timed: FinalBoss says it does not spoil, while VGC marks it as timed without a number. Deliver it promptly to be safe.
Full trading sequence, step by step
- Pocket Egg: as adult Link, talk to the Cucco Lady in Kakariko Village. She gives you the Pocket Egg, which hatches into the Pocket Cucco after a night passes.
- Pocket Cucco: take it to the man asleep in the house beside Kakariko’s staircase. The sleeper is Talon. If you have already won Epona, he has moved back to Lon Lon Ranch, so wake him there instead. Afterwards, return the Cucco to the Cucco Lady.
- Cojiro: the Cucco Lady swaps the Pocket Cucco for Cojiro, her brother’s blue Cucco. Take Cojiro into the Lost Woods and find the young man slumped against a tree stump.
- Odd Mushroom: he gives you the Odd Mushroom. The timer starts now. Run back to Kakariko and enter Granny’s potion shop through the back door in the alley behind the main potion shop.
- Odd Potion: Granny brews the Odd Potion. Head back to the same stump in the Lost Woods. The young man is gone; Fado, a Kokiri girl, takes the potion in his place.
- Poacher’s Saw: Fado gives you the Poacher’s Saw. Ride to Gerudo Valley, jump the broken bridge on Epona or Longshot across, and give the saw to the carpenter by the tent on the far side.
- Broken Goron’s Sword: the carpenter hands over the broken blade. Climb to the summit of Death Mountain Trail and show it to the giant Biggoron.
- Prescription: Biggoron cannot fix it because his eyes hurt, so he writes you a Prescription. Take it to Zora’s Domain.
- Eyeball Frog: thaw the frozen King Zora with bottled Blue Fire, then show him the Prescription. He gives you the Eyeball Frog. The second timer starts. Leave via Zora’s River, cross Hyrule Field on Epona and reach the Lakeside Laboratory at Lake Hylia.
- World’s Finest Eye Drops: the scientist turns the frog into eye drops. The third timer starts. Race back across Hyrule Field, through Kakariko and up Death Mountain Trail to Biggoron.
- Claim Check: Biggoron uses the drops and gives you the Claim Check while he works on the sword.
- Biggoron Sword: wait three in-game days, or play the Sun’s Song six times to pass three days and nights, then show Biggoron the Claim Check to collect the sword.
Tips and common stuck points
The Eye Drops run is the tightest. Before you hand over the frog, make sure Epona is waiting in Lake Hylia or Hyrule Field so you can mount immediately. On Death Mountain Trail, use your new jump and the sprint after a roll to cut corners, and clear Skulltulas on the climbing wall with the Hookshot rather than waiting for them to move.
If the young man in the Lost Woods is missing when you bring Cojiro, make sure you are adult Link and look near the stump close to the area where child Link met Skull Kid. If Granny is not in the shop, enter from the back alley entrance; the front of the main potion shop leads elsewhere.
You only need one sword out of this chain. If you already bought the Giant’s Knife from Medigoron in Goron City, the Biggoron Sword replaces it with an unbreakable version.
Is the Biggoron Sword worth it?
Yes, if you are comfortable without a shield. It is two-handed, so you cannot block while it is equipped, but it deals double the Master Sword’s damage and never breaks, unlike the Giant’s Knife. Remake tier lists rank it as the best optional damage upgrade. Note that the finishing blow on Ganon at the very end still uses the Master Sword.
Frequently asked questions
How long do you have to deliver the Odd Mushroom?
Two remake guides say four minutes on Switch 2; one still lists three. Treat it as three to be safe, and do not warp.
Can you use warp songs during the trading sequence?
Not during a timed delivery. Warping spoils the item and you must restart that step from the person who gave it to you.
How long do you wait for the Biggoron Sword?
Three in-game days after you receive the Claim Check. Playing the Sun’s Song six times skips the wait.
Where do I get Blue Fire for King Zora?
In the Ice Cavern, reached from Zora’s Fountain as adult Link. Scoop the blue flames into an Empty Bottle.
Does the Biggoron Sword break?
No. It is the unbreakable version of the Giant’s Knife, though it is two-handed and blocks you from using a shield.
