- Rainbow eggs are the highest-value steals during sea-parting runs.

- Rebirths multiply your cash multiplier and unlock late-game gear fast.
Best Animals Tier List for Open Sea For Animals
In Open Sea For Animals, your progress is driven by the animals you hatch from stolen eggs. Each animal generates income per second, and the gap between a common pet and a secret like the Hydra is enormous. The core loop is simple: train strength, part the sea, grab eggs before the water rushes back, hatch animals, and repeat. The best animals dramatically accelerate every stage of that loop.
Video Highlights:
- Starting fresh with the Hydra secret and reaching near-max upgrades in one session
- Dumbbell progression from starter weights up to the birthday cake and passenger plane
- Staff upgrades including the golden spatula, void staff, and mailbox
- Stealing rainbow and radioactive eggs from deep zones under time pressure
A single secret-tier animal like the Hydra can carry you from level one to max rebirths in one session, because its income per second dwarfs every common pet you hatch early on.
Based on in-game performance, here is how the top animals stack up:
| Tier | Animal | Approx. Income | Notes |
|---|---|---|---|
| S | Hydra (Secret) | ~4.7 quadrillion/sec | Best overall earner, trivializes early rebirths |
| A | T-Rex / Dinosaur | ~270 trillion/sec | Strong mid-to-late pet, solid backup |
| B | Elephant | ~15 trillion/sec | Great value from mammoth eggs |
| B | Diamond Ostrich | Mid trillions | Reliable early boost from ostrich eggs |
| C | Gold Gorilla | Low trillions | Event-timed gold egg pick |
| C | Common animals | Billions | Sell extras for quick cash |
Egg Rarities and Steal Priority
Not all eggs are worth the risk. When the sea parts, you have limited time and limited carry slots, so knowing which eggs to grab first is the difference between a huge payout and drowning with nothing.
| Rarity | Priority | Where Found |
|---|---|---|
| Rainbow | ★★★★★ | Deepest zones, rarest spawns |
| Radioactive | ★★★★ | Late-game areas, guarded zones |
| Eternal | ★★★★ | Cyber/special zones |
| Diamond | ★★★ | Mid-depth areas |
| Special | ★★★ | Scattered across zones |
| Gold | ★★ | Gold event spawns |
| Common (Ostrich, Snail, Mouse) | ★ | Starting areas |
Rainbow First
- Highest value eggs
- Prioritize deepest areas
- Requires max speed upgrades
Watch the Timer
- The wave returns fast
- Overloading on eggs slows your escape
- Know your carry limit
Luck Boosts
- Use luck potions before runs
- Times-two luck boosts rainbow spawns
- Stack with event multipliers
Grabbing one extra egg has cost countless runs. If the water is closing in, drop low-tier eggs and sprint — a radioactive egg beats drowning with six commons.
Step-by-Step: From Noob to Max Upgrades
This is the proven progression route for reaching max rebirths and top-tier animals efficiently.
Train Strength Early
Buy the best dumbbell you can afford and grind strength. Strength determines how far you can push the sea back, unlocking deeper egg zones.
Invest in Speed and Carry
At the upgrade stand, prioritize speed first, then carrying amount. Speed is expensive but mandatory for surviving deep-zone steals.
Steal and Hatch Strategically
Part the sea, run for rainbow or radioactive eggs, and place eggs at your base. Equip your best pets and sell the rest for cash.
Rebirth Aggressively
Each rebirth multiplies your cash rate. Chain rebirths early — going from times 4 to times 512 dramatically accelerates every later upgrade.
Climb the Equipment Ladder
Upgrade your staff through the tiers and your training weight from dumbbells up to the titanium car and passenger plane for massive strength gains.
You know you're near max when you've hit max rebirths, own the mailbox staff, train on the passenger plane, and consistently steal from the final area.
Equipment and Upgrade Comparison
Staff choice and training weight directly feed your strength stat, which gates how much of the map you can access.
| Staff | Tier | Highlight |
|---|---|---|
| Smacker | Starter | Basic water clearing |
| Golden Cobra / Pharaoh Wand | Early | First real upgrades |
| Star Wand | Mid | Solid glow and power |
| Galaxy Wand | Mid-High | Strong visual and output |
| Void Staff | High | Excellent deep-zone tool |
| Golden Spatula | Very High | Bright, powerful late pick |
| Mailbox | Best Base | Strongest standard staff |
| Mailbox + Secret Bonus | Best Overall | Beats every base staff |
| Training Weight | Strength Impact |
|---|---|
| Starter dumbbells | Millions of strength |
| Diamond dumbbell | Fast mid-game scaling |
| Birthday dumbbell (cake) | Quintillion-range strength |
| Titanium car | Late-game power spike |
| Passenger plane | Top-tier training, ~20+ quintillion strength |
Strength gamepasses stack up to times 4,000 multipliers. They are paid conveniences — the same stats are reachable through grinding rebirths if you'd rather stay free-to-play.
Farming Goals Checklist
Work through these milestones to fully unlock the game's best content.
Progression Milestones:
- Hatch a secret-tier animal (Hydra)
- Reach the diamond dumbbell upgrade
- Complete your first ten rebirths
- Unlock the mailbox staff
- Steal a rainbow egg from the final area
- Train on the passenger plane
Deep-zone NPCs guard premium eggs and respawn on a timer. If rainbow spawns are dry, farming guarded specials and radioactive eggs keeps income steady between waves.
FAQ
Q: What are the best animals in Open Sea For Animals?
The Hydra secret is the strongest earner at roughly 4.7 quadrillion per second, followed by the T-Rex at around 270 trillion per second and the Elephant at about 15 trillion per second. Any secret-tier animal outclasses commons by a massive margin.
Q: How do I get better eggs?
Upgrade strength to open deeper sea zones, buy speed upgrades to survive the return wave, and use luck potions or times-two luck boosts before runs. Rainbow eggs appear most often in the deepest areas.
Q: Should I rebirth early or keep my cash?
Rebirth early and often. Each rebirth multiplies your cash rate, and the multiplier compounds quickly — going from times 4 to times 512 in one session is achievable with a strong pet lineup.
Q: What does carrying amount do?
Carrying amount determines how many eggs you can hold during a single sea-parting run. The number shown near eggs is your current capacity, not a zone requirement.
