2. Hatch eggs and collect fish.
3. Use the money generated by fish.

This is a scope summary, not a step-by-step map walkthrough. The reviewed official description does not provide exact controls, locations, prices, income values, rarity order, hatch odds, timers, upgrade gains, or detailed stealing rules.

Use the information visible in your game

If the game shows an effective income rate, put that number and its displayed unit into the income calculator. To compare two lineups without treating missing rates as zero, use the tank planner. If you can see both an upgrade cost and the resulting income change, the payback tool can compare them.

What should you do next?

The progression guide turns the information you already have into a decision path. For the one confirmed movement mechanic, read the swim speed guide.
