Income per Second & Value
Reference income
On the community reference value, Koi is worth $12M/s — about $720M a minute, $43.2B an hour and $1.04T a day if the value holds. Above it in Cherry Blossom sits Stag at $145M/s. The next one down is Snowy Owl at $7.5M/s.
Treat the figure as the middle of a range. The roll that produces Koi is not fixed, so your own copy can land above or below it, and the value is a reference this site keeps rather than a quote anyone has to honour in a trade.
Size and Mutation variance
No verified multiplier for size or mutation exists on this site, so none is printed. Both apply on top of the base value, so treat $12M/s as the base rather than the ceiling. The income calculator multiplies the figure on this page instead of an invented bonus.
Rarity & Availability
Rarity label
Koi is Cosmic — one of the ten rarity labels this site uses, band 8 in its own ordering. 15 of the 20 pets carrying it have a confirmed value. A label like this groups pets, and the grouping cuts across collections: the pets sharing it are listed together on the Cosmic pets page.
Acquisition/source
It is an egg-pool pet, listed in the Cherry Blossom collection — Endgame tier, and it opens at 2.5B Speed. The collection is described in full on the Cherry Blossom page.
How to Get Koi
Egg or event source
No source name is asserted here for Koi — turning a collection name into an egg name is exactly the kind of guess that makes a pet page wrong. What is known is the pool: Cherry Blossom, listed on the Cherry Blossom table. The site prints no odds, because none could be verified.
Requirements/progression gate
Cherry Blossom opens at 2.5B Speed, and its guardian is Oni Tiger. Because hatching is done in the world, the gate decides access: below it, this pet is out of reach. Its tier labelling is Endgame. The whole ladder is on the Cherry Blossom page.

Practical use
It is not the top of Cherry Blossom: Stag is listed at $145M/s against its $12M/s, so within its own collection it is the option behind that one. At $43.2B an hour it is an endgame figure on this site's scale.
