Cosmic
Leviathan is a Cosmic pet in Roblox Steal an Egg that hatches from the Leviathan Egg. At normal size with no mutation it earns $220K/s — the 27th best of 28 Cosmic pets and 127th out of all 197 pets in the game.
How to get Leviathan
Reach about 900 Speed and travel to the Lake biome 🦢. Wait until the Swan guardian is asleep, grab the Leviathan 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.
