Follow the plot prompt: click and hold to dig up the egg, which can be a Common padlock. Put eggs on the plot so pets can earn cash, sell loot from the top bar, and equip the best shovel the shop will give you.
Which shovel is the strongest?
The Zero Shovel has the highest published Power, 30x, at a listed price of $200Qa. Until you can pay for it, equip the highest multiplier you already own. The HUD Power number is a separate stat from that multiplier.
Why does digging say it is slow?
The dig screen tells you to train Power or upgrade your shovel. Open the shop for a higher multiplier, or use the Dig Faster control if the next shovel is still too expensive. Standing on the warning does not fill the bar.
Do pets earn cash while I am offline?
Yes. The game description says you keep earning cash while offline, and the HUD prints Cash Earns Offline. Exact cash per pet is not published.
