+1 Drain Water Per Click
Draining your first pool
Step
When you start, a free water pump is already available. Every click raises the water level and works toward emptying the pool. Stopping partway through means you cannot collect the fish, so keep going until the pool is completely empty. Once the bottom is exposed, check it carefully so you do not leave any fish behind.
- Confirm the free pump is active before your first click.
- Click to fill the water level each click adds to the meter that drains the pool.
- Do not stop early fish only become collectible when the pool reaches zero.
- Check the pool floor to pick up every fish before moving on.
- Put high-earning fish into the aquarium and sell weaker or duplicate fish for cash.
- If you already have a pet, equip whichever gives the highest water multiplier.

Two things cash and water level actually do
Table
Water level and cash are separate values with completely different jobs. Knowing which resource is low tells you exactly what to fix.
| Water level | raised by clicking; multiplied by pumps and pets; used to drain pools. |
| Cash | earned by selling fish and collecting from the aquarium; spent on bag size, movement speed, and aura upgrades. |
| Pumps | the main tool for increasing how much water level each click adds. |
| Pets | equipped to stack an additional water multiplier on top of your pump. |
| Aquarium | holds fish that generate cash over time, not water level. |
| Bag | limits how many fish you can carry; expand it only once you feel the cap hurting you. |
Pump and pet priorities in the early game
Tips
When draining feels slow, the answer is almost always a stronger pump or a better pet. Upgrade the pump as soon as you meet its unlock condition, and always equip the pet with the highest water multiplier number regardless of its rarity name. Bag and speed upgrades matter, but only once you are actually running out of bag space or spending a lot of time walking back and forth.
- Replace your pump the moment you can afford the next one.
- Compare pets by their water multiplier number, not by rarity label.
- When water level feels stuck, check pumps and pets before spending cash elsewhere.
- When cash feels stuck, send high-earning fish to the aquarium and sell weak duplicates.
- Collect aquarium cash regularly — it piles up quietly and is easy to forget.
- Read the shop icons carefully so you never spend water level on a cash item or vice versa.
Sorting fish — aquarium versus selling
Check
You have two ways to turn fish into cash: sell them instantly or place them in the aquarium where they generate cash repeatedly over time. Aquarium slots are limited, so fill them by earnings value, not by looks or name. Before tapping the bulk-sell button, always check whether any high-value fish are about to get swept up by mistake.
- Aquarium slots filled by earnings value, highest first
- Duplicates sorted by value sell the lower-value copy, keep the stronger one
- Rare and mutant fish checked individually before any bulk sale
- Aquarium cash collected before it caps out
- Bag space cleared by selling the weakest fish when you run out of room
Mutant fish and weather events
WarnMutant fish carry multipliers on both their sell price and their aquarium earnings. There are four types: Gold, Diamond, Venom, and Hole, with Hole carrying the highest multiplier of the four. Poison weather raises the chance of Venom fish appearing, and Black Hole weather does the same for Hole fish. Each weather event lasts four minutes, so when one begins, pause any long drain or shopping trip, make sure your bag has free space, and search the map.

When to rebirth
Step
Rebirthing sets your water level back to zero in exchange for a long-term multiplier that stays with you. Going in under-prepared can leave you locked out of later areas for a long time.
- Check your pets and aquarium first they determine how fast you rebuild after the reset.
- Open the rebirth screen read which items reset and what multiplier you will receive before pressing anything.
- Confirm reset targets anything that resets is listed there; do not rely on memory.
Safe and healthy play
WarnEvery core mechanic — draining, fishing, upgrading pumps, building aquarium income — is available without spending Robux. Optional Robux purchases exist for some pumps and pets, but they are not required to progress. Because the game involves repetitive clicking, it is easy to lose track of time, so setting a play schedule before you start is a good idea.

Common questions
FAQWhy can't I collect fish even though I've been clicking for a while?
Fish only appear at the bottom of the pool once it has been drained completely. If you stop clicking before the water level reaches zero, no fish are available to collect. Keep going until the pool is fully empty, then check the floor for everything.
I sold fish but my water level didn't go up — what's happening?
Selling fish earns cash, which is an entirely separate resource from water level. Water level only rises when you click or tap the screen. To drain pools faster, upgrade your pump and equip a pet with a higher water multiplier.
A mutant fish disappeared before I could grab it — is that a bug?
Mutant fish can vanish if you leave them uncollected for too long. When a weather event starts, clear space in your bag and head straight for them rather than finishing other tasks first.
Can I reach the later areas without spending Robux?
Yes — draining, collecting fish, upgrading pumps, and building aquarium income are all available without spending Robux. Optional purchases exist but are not required. Consistently upgrading your pump, equipping the pet with the highest water multiplier, and keeping good fish in the aquarium is enough to keep progressing.
