Stealing it
- Nests reset every 5 minutes, so if the Royal Sphinx 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.
- Scorpion guards the nests in Desert. Grab and keep moving rather than stopping to inspect what you picked up.
