Biome 02 of 10
Lakebiome in Steal An Egg
The first real gate. 900 Speed is trivial once the treadmill is running, and Lake introduces the first Cosmic-tier pet in the game (Leviathan), which makes it worth farming longer than most players do.

One of each pet in this biome would earn $223K/s combined — though Leviathan alone accounts for 98% of that, which is the usual shape in this game: the top pet dominates its biome.

Where the game starts
Lake is the only biome with no Speed requirement, which makes it the one place the game lets you learn the loop without punishing you for it. Everything after this is the same four steps at higher stakes: take an egg, outrun the guardian, hatch it, spend the income on Speed.
The mistake that costs new players the most time is treating Lake as something to leave as fast as possible. It is not. Two things here compound:
- Index rewards. Hatching a species you have never owned pays out Speed and cash, and rarer first-timers pay more. Early on, a new species is worth more than another copy of one you already have — so hatch variety, not volume.
- The free 10,000 Speed. Liking the game, favouriting it and joining the group takes under a minute and clears the next gate outright. A surprising number of players grind for an hour before finding that panel.
The ceiling here is Leviathan at $220K/s. That is small against what comes later, but it is what funds the treadmill upgrades that get you out — and the treadmill is the only unlimited free source of Speed in the game.
The full opening sequence, in the order the steps actually matter, is in the beginner guide.
The Swan
The Swan patrols open water where there is little cover, so the danger is not its speed but the lack of anywhere to break line of sight. Plan the exit before you pick anything up.
Guardian behaviour is a player observation rather than a published figure, so this is written as commentary, not data. It carries no sourcing badge because there is no source to cite — if your experience differs, tell us.

The Swan. Meeting the minimum Speed does not mean you can outrun it, especially while slowed by a large egg.
What is the best pet in Lake?
Leviathan, a cosmic pet earning $220K per second before mutations.
