Companions in 100 Days at Sea pull passive weight through a full Day 100 run, whether that means bringing you food, patching your health, slowing enemies, or padding your damage. Not every pet earns its Pearls, though. Some rolls carry a run on their own, while others hand you a stat bump so small you will forget it is equipped. The ranking below sorts every companion by how much it moves a real survival run in the July 2026 meta after the Ice Region update.
Quick answer: Snowman (Ice Chest) is the strongest companion because its 20% enemy slow makes every fight more survivable. Seagull and Crow both auto-fetch food every 120 seconds, and Penguin generates bandages, so chase those first. Polar Bear is the most reachable combat pet at a 30% Ice Chest drop.
Companions are pulled from chests (Fisherman’s, Warrior, Pirate, Magma, and Ice), and each chest holds a fixed pool with set drop odds. Rankings weigh three things: how directly the effect keeps you alive, how strong the number is versus other pets, and how realistic the drop chance is. Rarer pets need a bigger payoff to justify the roll.
100 Days at Sea companion tier list
| Tier | Companions |
|---|---|
| S | Snowman, Seagull, Crow, Penguin |
| A | Swordfish, Pirate Gunner, Magma Golem, Polar Bear, Arctic Wolf |
| B | Octopus, Salamander, Shark, Dolphin, Whale |
| C | Parrot, Lava Snail, Orca, Cat, Turtle |
| D | Frog, Snorf, Crab |
S tier: survival-defining companions
These four hit the two problems that actually end runs, which are running out of food and dying in combat. Snowman is the single best pet in the game. Slowing every enemy by 20% buys reaction time in tight fights and turns dangerous encounters into manageable ones. Seagull and Crow both haul in food on a 120-second timer, which erases one of the constant pressures of a long survival run. Penguin quietly builds a bandage every 220 seconds, a healing source that keeps compounding the deeper you push.
| Companion | Chest | Drop Chance | Effect |
|---|---|---|---|
 Snowman | Ice | 5% | Slows enemies by 20% |
 Seagull | Pirate | 30% | Brings food from environment every 120 seconds |
 Crow | Magma | 30% | Brings food from environment every 120 seconds |
 Penguin | Ice | 5% | Creates a bandage every 220 seconds |
A tier: strongest combat boosts
A tier is where the biggest raw damage numbers live. Swordfish, Pirate Gunner, and Magma Golem all sit at a 5% drop chance, but their 10% damage boosts are the highest combat increases in the pool, which justifies the rarity. Polar Bear matches the same 10% melee boost at a far friendlier 30% Ice Chest drop, making it the go-to realistic target for a combat build. Arctic Wolf rounds out the group with a 10% running speed increase, useful for kiting and covering island ground.
| Companion | Chest | Drop Chance | Effect |
|---|---|---|---|
 Swordfish | Warrior / Pirate | 5% | Increases melee damage by 10% |
 Pirate Gunner | Pirate | 5% | Increases pistol damage by 10% |
 Magma Golem | Magma | 5% | Increases melee damage by 10% |
 Polar Bear | Ice | 30% | Increases melee damage by 10% |
 Arctic Wolf | Ice | 30% | Increases running speed by 10% |
B tier: solid but second-choice pets
B tier companions are all genuinely useful, but each one is either a slightly weaker version of a better pet or covers a narrower situation. Octopus and Salamander both fetch items instead of food, which is handy without being run-saving. Shark, Dolphin, and Whale hand out 7.5% boosts to melee damage, speed, and health, so they hold value if that is the stat you need and the roll cooperates.
| Companion | Chest | Drop Chance | Effect |
|---|---|---|---|
 Octopus | Warrior | 16% | Brings an item from environment every 120 seconds |
 Salamander | Magma | 5% | Brings an item from environment |
 Shark | Fishermans / Warrior | 13% / 16% | Increases melee damage by 7.5% |
 Dolphin | Fishermans / Magma | 13% / 30% | Increases running speed by 7.5% |
 Whale | Pirate | 30% | Increases health by 7.5% |
C tier: outclassed fillers
Nothing here is broken, but each pet is beaten by a better option from the same or a nearby chest. Parrot, Orca, and Cat all give small speed or damage nudges, while Lava Snail trims hunger and Turtle adds a little health. Equip one if it drops, but do not burn Pearls hunting for these on purpose.
| Companion | Chest | Drop Chance | Effect |
|---|---|---|---|
 Parrot | Pirate | 30% | Increases pistol damage by 7.5% |
 Lava Snail | Magma | 30% | Reduces hunger by 7.5% |
 Orca | Ice | 30% | Increases running speed by 7.5% |
 Cat | Warrior | 32% | Increases running speed by 5% |
 Turtle | Fishermans | 25% | Increases health by 5% |
D tier: skip these
The weakest effects in the game land here. Frog, Snorf, and Crab each offer a 5% bonus that barely registers in a serious run. They come from the low-tier Fisherman’s and Warrior chests, so you may end up with one early, but there is no reason to keep rolling for them.
| Companion | Chest | Drop Chance | Effect |
|---|---|---|---|
 Frog | Fishermans | 25% | Reduces hunger by 5% |
 Snorf | Warrior | 32% | Increases health by 5% |
 Crab | Fishermans | 25% | Increases firearm damage by 5% |
Which chest to open for your situation
The right companion depends on what is killing you. If food and health are your constant struggle, aim for Seagull from the Pirate Chest or Crow from the Magma Chest. If you keep dying in fights, Polar Bear from the Ice Chest at a 30% drop is the most accessible high-value combat pet you can realistically land. The Ice Chest is the standout buy for combat or utility rolls, since Snowman and Penguin also live there, even at their 5% odds.
Companion drops are RNG, so tier letters describe average value rather than any single roll. Equip a pet in the lobby before you start a run, and confirm it is active by checking that its perk shows in your loadout. Save your Pearls for the chest that matches your current need, and if Snowman ever shows up, take it. This ranking reflects the July 2026 Ice Region meta, and placements can shift when Stranded Devs pushes new biome or chest updates.
