100 Days at Sea Companion Tier List – Every Pet Rank

If you’ve finally saved up a decent pile of Pearls in 100 Days at Sea, there’s one question that starts getting surprisingly difficult: which Companion should you actually spend them on?

At first, I thought most pets would just give small passive bonuses and that the difference wouldn’t matter much. That’s definitely not the case. A good Companion can quietly solve an annoying part of your run for you, whether that means bringing back food, generating healing supplies, helping you move faster, or giving you an edge when enemies start becoming a problem.

And then there are a few pets where the bonus looks fine on paper, but once you compare it with what the better Companions are doing, it’s hard to justify spending Pearls specifically trying to get them.

So, I’ve ranked every Companion from S Tier down to D Tier below. I’m looking at how useful their bonuses actually are during a normal survival run, rather than simply ranking them by rarity.

Here’s my overall ranking before we get into why each Companion is sitting where it is.

There’s an important thing to keep in mind here: a lower-tier Companion isn’t automatically useless.

If you already own one, use it. Free stats are free stats. This ranking is more about deciding which Companions are worth actively chasing and spending your Pearls on.

These are the Companions I’d be happiest to pull. Their abilities either have a noticeable effect on survival or provide recurring resources that continue helping throughout the run.

Snowman earns an easy S Tier spot because it can slow enemies by 20%.

Twenty percent might not sound enormous until you actually have enemies chasing you. That extra breathing room gives you more time to reposition, attack, escape, or simply figure out what you’re doing before something reaches you.

That makes Snowman particularly useful during dangerous encounters where one bad movement can put you in serious trouble.

Unlike a tiny stat increase, enemy slowing is also something you can actually feel while playing. If you manage to unlock Snowman, I’d absolutely give it a chance before swapping it out for a basic damage or movement Companion.

Seagull is one of my favorite practical Companions because it tackles something you’re going to worry about throughout practically the entire adventure: food.

Every 120 seconds, Seagull automatically brings food from the environment.

You don’t have to change the way you play to benefit from it. Just keep surviving, and your Companion periodically helps with your food supply in the background.

That saves time you would otherwise spend gathering resources yourself. The longer your run continues, the more useful that passive collection becomes.

For players who constantly find themselves worrying about hunger, Seagull is easily one of the best Companions to target.

Crow sits alongside Seagull for basically the same reason.

It can also bring food from the environment every 120 seconds, giving you another excellent option if you want passive food gathering.

The big difference when deciding between Crow and Seagull is where you’re trying to get them from. Seagull comes from the Pirate Chest, while Crow is associated with the Magma Chest.

So rather than saying one is dramatically better than the other, I’d choose whichever chest makes the most sense for the other Companions you’re interested in.

Either way, automatic food gathering is incredibly convenient.

Penguin takes a different approach to survival.

Instead of feeding you, Penguin creates a Bandage every 220 seconds.

I really like this ability because healing supplies are one of those resources you don’t think much about until you suddenly need them. Having Bandages generated automatically gives you a steady source of recovery without requiring you to constantly search for additional supplies.

The 220-second wait means you’re not going to be drowning in Bandages, of course. But over a longer adventure, those free heals start adding up.

If taking damage is causing more failed runs than hunger, Penguin could actually be more useful to you than Seagull or Crow.

A Tier is where we start getting into some excellent combat and mobility options.

They aren’t quite as universally useful as my S Tier picks, but several of these can become extremely strong when paired with the right playstyle.

Swordfish provides a 10% damage increase based on its associated weapon type.

A 10% increase is significant enough to matter, especially if you’re consistently using the weapon that benefits from it.

The catch is availability. Swordfish only has around a 5% drop chance, so this isn’t necessarily a Companion you should expect to pick up immediately.

Still, if you get it and its damage bonus matches the weapons you prefer using, it’s a very strong Companion.

Pirate Gunner is another damage-focused A Tier option, providing a 10% damage increase for its corresponding weapon type.

This is the kind of Companion that rewards specialization.

If you’re regularly fighting with the weapon type it improves, that 10% bonus stays relevant whenever combat starts. If you’re constantly swapping between completely different weapon types, however, its value becomes a little more situational.

Pirate Gunner also has roughly a 5% drop chance, making it one of the rarer damage Companions.

Magma Golem follows the same general idea, offering another 10% weapon-specific damage bonus.

Again, the important part isn’t simply seeing “+10%” and immediately equipping it. Make sure you’re actually using the weapon type that benefits from the effect.

When you are, Magma Golem is excellent.

It also comes with that low 5% drop chance, though, so getting one may take some luck.

Now this is the A Tier Companion I’d pay particular attention to.

Polar Bear increases melee damage by 10%, which is already a very respectable combat bonus.

What makes it more attractive is its availability. Polar Bear reportedly has a 30% drop chance from the Ice Chest, compared with the 5% chance attached to some of the rarer damage-focused Companions.

That combination makes it a really sensible target.

You aren’t necessarily chasing the absolute rarest pet in the game; you’re chasing a strong, practical damage boost that you have a reasonable chance of actually obtaining.

For melee players, Polar Bear is one of the first Companions I’d look for.

Arctic Wolf increases your running speed by 10%.

Movement bonuses are easy to underestimate because they don’t produce a giant damage number on screen. But think about how often you’re moving compared with how often you’re fighting.

Faster running helps with exploration, travelling between objectives and, importantly, getting away from situations that have gone completely wrong.

It’s useful without requiring a particular weapon or combat setup, which is why Arctic Wolf comfortably makes A Tier for me.

B Tier isn’t where the bad pets begin.

These Companions are still perfectly usable. The problem is that most of them either provide smaller versions of stronger bonuses or don’t have quite enough impact to compete with S and A Tier.

Octopus can bring an item from the environment every 120 seconds.

I generally like abilities that generate resources automatically because they continue working while you’re busy doing something else.

Octopus therefore has genuine utility, particularly across longer runs.

It’s just harder to rank above Companions such as Seagull and Crow when food is such a consistently important survival resource.

Salamander offers a similar kind of utility-focused benefit.

That makes it another solid passive Companion rather than something that completely changes how you approach combat.

If you already have Salamander, there’s no reason to dismiss it. I just wouldn’t prioritize it ahead of the strongest S or A Tier targets when deciding where to spend limited Pearls.

Shark increases melee damage by 7.5%.

That’s actually pretty decent.

The reason Shark lands in B Tier becomes obvious when you put it next to Polar Bear. Polar Bear offers a 10% melee damage increase, meaning Shark essentially fills the same role but with a weaker bonus.

Until you get Polar Bear, though, Shark is a perfectly good melee Companion.

Dolphin gives you a 7.5% running speed increase.

Once again, that’s useful. More speed makes exploration smoother and gives you better mobility when escaping enemies.

But Arctic Wolf gives you a 10% running speed increase.

So Dolphin ends up in the slightly awkward position of being good while also having a clearly stronger alternative above it.

If Dolphin is your best movement Companion right now, I’d happily use it.

Whale increases your maximum health by 7.5%.

Extra health is never a bad thing in a survival game. It gives you a little more room for mistakes and can sometimes be the difference between surviving another hit and losing the run.

I wouldn’t chase Whale before the best utility or damage Companions, but it’s one of those straightforward bonuses that will always provide some value.

C Tier is where I’d stop deliberately spending Pearls just to hunt a specific Companion unless there’s a particular reason you want it.

These pets still provide bonuses, but most have stronger alternatives elsewhere.

Parrot increases pistol damage by 7.5%.

If pistols are your main weapon, that’s a respectable little boost and certainly better than using a Companion that doesn’t complement your build.

The problem is that the higher tiers contain stronger damage options.

I’d use Parrot if I had it, but I wouldn’t make it my long-term target.

Lava Snail reduces hunger by 7.5%.

On paper, this sounds perfect for survival. And it does help.

My issue is that if hunger management is the reason I’m choosing a Companion, I’d much rather have Seagull or Crow automatically bringing me food every 120 seconds.

Those Companions directly contribute resources rather than simply making hunger drain slightly easier to manage.

Lava Snail isn’t bad; it’s just competing against some fantastic food-related alternatives.

Orca provides a 7.5% running speed increase.

That puts it into similar territory as Dolphin.

Mobility is always handy, but Arctic Wolf’s 10% running speed bonus gives you a better version of essentially the same benefit.

If you pull Orca first, use it. Once Arctic Wolf becomes available, you’ll probably want to upgrade.

Cat increases movement speed by 5%.

I have a soft spot for movement bonuses because even small increases can make general gameplay feel nicer. But at only 5%, Cat has trouble competing with the stronger movement-focused Companions.

This is a classic “nice to have, not worth chasing” pet.

Turtle increases your health by 5%.

Extra health helps, but 5% isn’t enough for me to recommend specifically spending Pearls trying to obtain Turtle.

Whale already offers a stronger 7.5% health increase, while higher-ranked Companions can provide bonuses that have a much larger effect on your survival.

Still, if Turtle is one of your first Companions, there’s nothing wrong with taking the free health.

Now we reach the Companions I’d avoid actively chasing.

That doesn’t mean you need to throw them away the moment you unlock them. Early on, even a small bonus is better than nothing.

But once Pearls become something you’re deliberately investing, these pets simply don’t offer enough compared with the alternatives.

Frog reduces hunger by 5%.

Unfortunately, that’s a very small improvement compared with the food support available from S Tier Companions.

Seagull and Crow can automatically collect food every 120 seconds, while even Lava Snail provides a larger hunger-related percentage bonus.

Frog can help at the beginning, but I’d replace it fairly quickly.

Snorf provides 5% additional health.

That’s not completely useless, particularly if you’re still building your Companion collection.

However, Whale provides a 7.5% maximum health increase, and other high-tier pets offer much more impactful survival effects.

Use Snorf when it’s what you’ve got. Don’t burn through Pearls specifically hunting for it.

Crab increases firearm damage by 5%.

The same problem appears here.

Five percent extra damage is still technically an improvement, but there are considerably stronger damage Companions available.

If Crab happens to fit your current firearm setup, equip it until something better arrives. As a long-term target, though, it doesn’t make much sense.

This is where I’d actually move away from blindly following the tier list.

The “best” Companion depends somewhat on what’s killing your runs.

Struggling with food? Go after Seagull or Crow. Their ability to bring food every 120 seconds continues paying off throughout the adventure, and removing some of the pressure around hunger makes the whole survival loop easier.

Struggling in combat? Polar Bear is one of the more sensible targets, especially for melee players. You get a 10% melee damage bonus and a reported 30% chance from the Ice Chest, making it considerably more obtainable than some of the 5% damage pets.

Taking too much damage? I’d seriously consider Penguin. Automatically receiving a Bandage every 220 seconds isn’t flashy, but having another source of healing can rescue a run.

And if you manage to pull Snowman, definitely try it. Slowing enemies by 20% is one of those bonuses that makes much more sense once you experience it during a difficult fight.
