Stud Koi guide
If you are after a heavy catch from the LEGO® Event 2025, Stud Koi is the one to look for. Use Stud Bait in any weather and you can pull up a koi with shimmering orange studs that the wiki calls a masterpiece of the sea. It is rated Limited, but the data lists it as obtainable, so check that the event is active before you plan around it.
Size is its strength. Average weight is 122.5 kg with a range from 55 to 399 kg, and its maximum ranks 204 of 663 fish with a recorded maximum. The sale price is less impressive: C$2.89 per kg, about C$355 on average, which is 427 of the 742 documented fish. Base XP is 280.
That low rate per kilo is the key to reading this fish. A big body does not turn into big money here, so landing a 300 kg specimen feels better than it pays. Crab Stud, Glow Brick, Cardinal Studfish, Brickhorse, Clown Brickfish and Goldbrick are the other Limited catches in the event zone, and they are the ones to weigh it against.
Verdict: pick it for a large catch in your collection or a high-weight record. If the goal is quick coins, the per-kg rate says this is not the best use of your Stud Bait.
