Where you find it
The Leviathan Egg spawns in Lake and nowhere else. Lake is area 2 of 11 in progression order. You need 900 Speed to enter. The guardian there is Swan, and nests reset every 5 minutes.
How it ranks in Lake
This is the top of the Lake pool. The next-best egg in the area is Axolotl at $2.8K/s, so this is the egg to hold out for.

Stealing it
- Nests reset every 5 minutes, so if the Leviathan Egg is not up when you arrive, waiting for the reset is usually faster than travelling to another area.
- Colour varies between spawns and does not affect the income of the pet inside — identify the egg by its shape, not its colour.
- Bigger eggs are worth more but are heavier and slow you down. If you are close to the Speed requirement, a large egg can turn a safe run into a failed one.
- Swan guards the nests in Lake. Grab and keep moving rather than stopping to inspect what you picked up.
