100 Days at Sea Companion Guide – How to Unlock the Best Pets and Which Ones to Choose

Companions are one of the most valuable features in 100 Days at Sea, the Roblox survival game where players must survive for 100 days while exploring a vast ocean. These animal companions do much more than follow your character around—they provide passive abilities that can make gathering resources, finding food, and surviving much easier.

Whether you’re just starting your adventure or looking for the strongest companion to unlock next, this guide covers everything you need to know about getting Companions, earning Pearls, and choosing the best options for both beginners and long-term progression.

What Are Companions in 100 Days at Sea?

Companions are pets that accompany your character throughout your journey. Every Companion comes with its own passive ability, allowing it to assist you in different aspects of survival without requiring constant interaction.

Some Companions automatically collect food from nearby areas, while others provide benefits that improve overall efficiency during exploration. Since these passive effects remain active while you’re playing, unlocking powerful Companions can significantly reduce the time spent managing essential survival needs.

Because of these advantages, Companions are considered one of the most worthwhile upgrades in the game.

How to Get Companions

Companions are obtained by opening Companion Chests, which can be purchased using Pearls, the game’s premium currency. To unlock a Companion:

• Enter the 100 Days at Sea lobby.
• Open the Companion Shop.
• Choose the Companion Chest you want.
• Make sure you have enough Pearls.
• Purchase the Chest.
• Open it to receive a random Companion.

Each Companion Chest contains a different selection of pets with its own drop rates, so choosing the right chest is important if you’re hunting for a specific Companion.

All Companion Chests

There are currently five Companion Chests available, each offering different Companion pools and prices.

Fisherman’s Chest

• Cost: 40 Pearls

The Fisherman’s Chest is the most affordable option, making it an excellent starting point for new players. Since it costs far fewer Pearls than the other chests, you can open multiple copies while building your first Companion collection.

If you’re still learning the game or saving premium currency, this chest offers the best overall value.

Warrior Chest

• Cost: 80 Pearls

The Warrior Chest features Companions designed to improve combat and survivability. Players who frequently battle enemies may find these Companions useful as they progress into more challenging stages of the game.

Although more expensive than the Fisherman’s Chest, it provides stronger options for players looking to strengthen their overall survival capabilities.

Ice Chest

• Cost: 120 Pearls

The Ice Chest contains themed Companions with unique passive abilities. These pets offer specialized bonuses that can improve different aspects of exploration and long-term survival.

Because of its higher price, it’s generally recommended after you’ve already secured a few reliable Companions.

Pirate Chest

• Cost: 120 Pearls

The Pirate Chest is one of the most sought-after Companion Chests because it contains the highly desirable Seagull.

Many experienced players prioritize this chest thanks to Seagull’s excellent passive ability, making it one of the strongest long-term investments for survival.

Magma Chest

• Cost: 120 Pearls

The Magma Chest offers another top-tier Companion: Crow.

Like the Pirate Chest, it’s aimed at players looking for powerful passive abilities that remain useful throughout the entire game rather than only during the early stages.

Best Companion Chest for Beginners

If your supply of Pearls is limited, spending them carefully is the smartest strategy.

The Fisherman’s Chest is generally the best choice for beginners because:

• It has the lowest Pearl cost.
• You can open more chests with fewer resources.
• It helps expand your Companion collection early.
• It’s an efficient way to begin building your account.

Rather than saving for expensive chests immediately, new players can establish a solid foundation by collecting several Companions through this affordable option.

Best Companions for Long-Term Survival

While many Companions offer useful passive effects, two stand out as excellent long-term choices for almost every player.

Seagull

The Seagull is available from the Pirate Chest. Its passive ability automatically gathers food from the surrounding environment approximately every 120 seconds. This greatly reduces the amount of manual food gathering required, allowing players to spend more time exploring islands, completing objectives, or collecting valuable resources. For extended survival sessions, Seagull becomes one of the most convenient Companions in the game.

Crow

The Crow can be obtained from the Magma Chest. Like Seagull, Crow automatically collects food roughly every 120 seconds, helping maintain your food supply with minimal effort. Its passive effect becomes increasingly valuable during the later days of a survival run when food management becomes more demanding and efficient automation can save significant time.

How to Get More Pearls

Since every Companion Chest requires Pearls, collecting this premium currency should become part of your regular progression.

You can earn Pearls through several methods:

• Redeeming active game codes
• Completing quests
• Unlocking achievements and badges
• Claiming daily login rewards
• Joining the official developer group
• Purchasing Pearls from the Pearl Shop

The more Pearls you accumulate, the more Companion Chests you can open, increasing your chances of obtaining rare and powerful pets.

Are Companions Worth Unlocking?

Absolutely. Although they may seem like cosmetic companions at first, their passive abilities provide meaningful gameplay benefits that continue working throughout your survival journey. Companions can help you:

• Gather food automatically
• Reduce survival management
• Improve exploration efficiency
• Save time during long sessions
• Strengthen your overall progression

Because these benefits remain active continuously, investing in strong Companions pays off over the course of an entire 100-day run.

Companions are one of the most impactful progression systems in 100 Days at Sea, offering passive abilities that make survival considerably easier. Players can unlock them by purchasing Companion Chests with Pearls earned through quests, achievements, daily rewards, redeem codes, developer group bonuses, or the Pearl Shop.

For beginners, the Fisherman’s Chest provides the best value thanks to its low cost, while experienced players should aim for Seagull from the Pirate Chest or Crow from the Magma Chest. Both Companions automatically collect food at regular intervals, making them outstanding choices for long-term survival and reducing one of the game’s biggest challenges.
