Koi is a Cosmic pet in Roblox Steal an Egg that hatches from the Koi Egg. At normal size with no mutation it earns $12M/s — the 9th best of 28 Cosmic pets and 93rd out of all 197 pets in the game.
How to get Koi
Reach about 2.5B Speed and travel to the Cherry Blossom biome 🌸. Wait until the Oni Tiger guardian is asleep, grab the Koi Egg from the nest and run back to your pen before you get caught. Nests reset every 5 minutes, and bigger eggs are worth more but make you slower — so bring extra Speed.
