The Walnut Room, Ginger Island
In the Walnut Room of Ginger Island, Qi gives you a fishing quest called The Extended Family. The Order’s description notifies you that “Family members of the legendary fish have returned. You have three days to catch Ms. Angler, Glocierfish Jr., Son of Crimsonfish, Radioactive Carp, and The Legend II.” By doing so, you earn 20 Qi Gems.
How to Complete the Extended Family Order
You must catch the family members of 
Angler
, 
Crimsonfish
, 
Glacierfish
, 
Legend
, and 
Mutant Carp
. Unlike other legendary fish, the extended family variants spawn irrespective of the season and weather. To complete the quest, you must fish in the same spots where you found the original legendary sea creatures.
Extended Family Legendary Fish Locations
Here’s where to find each member of the extended family:
Ms. Angler
Head north of Joja Mart to find a narrow waterway with a small bridge. Here, you have the opportunity to catch Ms. Angler, the alternative variant of the legendary Angler. To enhance your chances of a successful catch, position yourself on the bridge and cast your fishing line in the opposite direction of the stream.
Glacierfish Jr.
In the Cindersap Forest, there is a triangle-shaped island in the water. To have a shot at catching the 
Glacierfish Jr.
., stand on this island and fish in the surrounding water. For an added advantage, position yourself on the rightmost corner of the land.
Son of Crimsonfish
Repair the broken bridge on the Beach to gain access to the Eastern Pier, a location crucial for fishing for rare creatures. The repair project demands 300 pieces of Wood. After successfully fixing the bridge, start fishing in the Ocean from the Eastern Pier to catch the elusive 
Son of Crimsonfish
.
Radioactive Carp
You can find the 
Radioactive Carp
in The Sewers. If you haven’t unlocked this area yet, donate 60 items to the Museum. Upon achieving this goal, you will be rewarded with the Rusty Key, which opens the door to The Sewers, where you can fish for Mutant and Radioactive Fish.
Legend II
The 
Legend II
is located in Mountain Lake, near the tent. Access the small islands in the middle of the pond and throw your hook toward the southern parts of the waterway to catch the last member of the extended family and finish Qi’s quest.
The Iridium Rod, Curiosity Lure, Lead Bobber, and Wild Bait are essential items for the Extended Family Quest. These fishing boosters increase the chances of finding rare sea creatures, helping to speed up the Order’s progress.
The Stardew Valley 1.6 update introduced several new fishing tools that can further improve the odds of catching legendary fish and completing the Extended Family Quest more efficiently. The following items from this update are recommended for those aiming to beat the quest with maximum efficiency:
Sonar Bobber
: This new Tackle lets you see the fish before deciding to catch it, preventing time wasted on the fishing mini-game if the catch isn’t the one you’re targeting.
Advanced Iridium Rod
: This item allows you to equip two Tackles, and the best part is that their effects stack, boosting your fishing efficiency.
Lucky Purple Shorts: If you place Mayor Lewis’s underwear in the first Tackle slot of the Advanced Iridium Rod, it will preserve the durability of the secondary Tackle.
Can You Repeat the Extended Family Quest?
The Extended Family Order appears periodically in Qi’s Walnut Room. It may take some time before the quest reappears on the list, but it’s possible to complete it multiple times within the same playthrough.
Veteran players often use the Extended Family quest as a strategy to catch as many legendary fish as possible. By avoiding the last fish, they can continue farming the others throughout the quest’s duration, resulting in massive profits. For example, catching multiple Legend II fish, smoking them, and selling each can net you around 20,000g to 30,000g each.
