The Mutant Carp is the Legendary Fish of The Sewers. It has the loosest rules of all the Legendary Fish. It bites in every season, at any hour and in any weather, and it bites at any Fishing level. The challenge lies in getting into The Sewers at all, and then in holding on once it bites. As with every Legendary Fish, it can be caught just once per save file, or once per player in Multiplayer. It counts towards the Master Angler achievement, and in a Fish Pond it produces valuable roe.

The in-game description reads: The strange waters of the sewer turned this carp into a monstrosity.

Catching

Donating 60 items to the Museum earns the Rusty Key, which unlocks The Sewers.

Once inside, any patch of sewer water will do, cast from any spot along the edge. Each cast has a one in ten chance of hooking the Mutant Carp. A Curiosity Lure doubles that chance, which makes it the best tackle for the search. Ordinary Carp share the water, so expect a few of those before the legend appears.

Hooking it is only half the job. The Mutant Carp has dart behaviour and a high difficulty. It jumps up and down the bar in big, sudden bursts, trying to shake the line. Chasing every jump tends to lose the fish. A steadier approach works better: keep the green bar near the middle and make small corrections, then follow the fish when it settles at the top or the bottom.

An Iridium Rod helps, since it holds bait and tackle at once. A Trap Bobber slows the meter when the fish slips out, and a Cork Bobber makes the green bar larger.

Prices

The Mutant Carp shares its sell price with the Glacierfish. That price doubles at iridium quality, and the Fisher or Angler profession raises it by a further quarter or half. A Fish Smoker doubles the value again while keeping the quality, so a smoked normal Mutant Carp sells for 2,000g.

Since only one can be caught, selling it is a one-time payout. A Fish Pond earns more over time. The pond holds a single Mutant Carp and can never be enlarged. That one fish produces Mutant Carp Roe on a good share of days, and a single harvest can hold several roe worth 530g each. A Preserves Jar turns the roe into Aged Roe worth 1,060g.

Sell prices by quality, with the bonus from each profession.

Quality	Price	Fisher (+25%)	Angler (+50%)
Normal	1,000g	1,250g	1,500g
Silver	1,250g	1,562g	1,875g
Gold	1,500g	1,875g	2,250g
Iridium	2,000g	2,500g	3,000g

Uses

The Master Angler achievement needs every original Legendary Fish, and the Mutant Carp is one of them. Earning it brings a letter from Willy with a Stardrop inside. Its relative, the Radioactive Carp, is a separate catch for Mr. Qi's "Extended Family" quest. While that quest is active, the original cannot be hooked, because the Radioactive Carp takes its place.

The Mutant Carp counts as "any fish" for Sashimi, Maki Roll and Quality Fertilizer. Using it there wastes almost all of its value. In the dye pots at Emily and Haley's house, it serves as a green dye. A Bait Maker can turn it into Mutant Carp Bait, though the fish is worth far more kept or sold.

Gifts

The Mutant Carp makes a poor gift. Among those who feel neutral about Mutant Carp are Elliott and Sebastian. Willy and Leo feel neutral about it as well, as do Demetrius, Linus and Pam.

The Dwarf, Krobus, Sandy and the Wizard count Mutant Carp as a disliked gift. So do Jas and Vincent. Caroline, George, Jodi, Kent and Lewis dislike it as well, as do the bachelors and bachelorettes Abigail, Alex, Emily, Harvey, Leah, Maru, Penny, Sam and Shane. The shopkeepers Clint, Gus, Marnie and Robin also dislike it.

Evelyn, Haley and Pierre hate it.

Notes

Bring a Curiosity Lure and plenty of energy on the first trip. The hook chance is low, so it can take many casts before the Mutant Carp bites. Build a Fish Pond beforehand so the fish has a home straight away.
