100 Days At Sea companion tier list: best pets to equip

You only equip one companion at a time in 100 Days At Sea. Match the buff to the problem that is actually ending your run.

On a normal Day 1 to 100 survival route, chase wipe-prevention pets first (Snowman, Crow, Seagull, Penguin), then rare automation (Salamander), then best combat when fights matter (Pirate Gunner or a +10% melee pet). Food-starved sails want food pets. Island and boss fights want gun or melee. Loot chore pressure wants Salamander.

Companions unlock from Pearl chests in the Companion Shop, not by buying a named pet. Full buff text, chest pools, and drop chances live on the companions collection. Pearls also compete with classes, and 100 Days At Sea codes can help stock up.

S Tier

Image	Companion	Role	Buff	Chest / cost	Why it ranks
	Snowman	Crowd Control	Slows nearby enemies by 20%	Ice / 120 Pearls	Unique slow that buys time in messy fights
	Penguin	Healing	Spawns a bandage every 220 seconds	Ice / 120 Pearls	Free heal items on a timer
	Crow	Food Gather	Brings food every 120 seconds	Magma / 120 Pearls	Stops hunger wipes on long sails
	Seagull	Food Gather	Brings food every 120 seconds	Pirate / 120 Pearls	Same food loop as Crow from Pirate Chest
	Salamander	Loot	Picks up and delivers loot nearby	Magma / 120 Pearls	Rare loot pickup automation
	Pirate Gunner	Gun Damage	+10% gun damage	Pirate / 120 Pearls	Best listed gun buff

S Tier holds the pets that either stop wipe pressure or are honestly best at one rare job. Snowman, Crow, Seagull, and Penguin keep runs alive when control, food, or healing is the real problem. Salamander clears loot chores instead of stacking another damage percent. Pirate Gunner is the gun ceiling when ranged fights are your plan.

If you are Pearl-tight, do not force Magma or Pirate rares first. Open Fisherman's and Warrior for usable mid buffs, then spend 120-Pearl chests on the role you still lack. Food pressure points Pirate or Magma for Seagull or Crow. Gun builds want Pirate. Loot pressure wants Magma for Salamander. Kite-heavy fights want Ice for Snowman or Penguin.

A Tier

Image	Companion	Role	Buff	Chest / cost	Why it ranks
	Swordfish	Melee Damage	+10% melee damage	Warrior or Pirate / 80-120 Pearls	Top melee line; rare from two chests
	Magma Golem	Melee Damage	+10% melee damage	Magma / 120 Pearls	Same +10% melee ceiling from Magma
	Polar Bear	Melee Damage	+10% melee damage	Ice / 120 Pearls	Same +10% melee as a common Ice roll
	Octopus	Materials	Brings materials every 120 seconds	Warrior / 80 Pearls	Strong materials timer at mid chest cost
	Arctic Wolf	Sprint	+10% sprint speed	Ice / 120 Pearls	Highest listed sprint buff

A Tier is the combat and mobility ceiling once wipe pressure is handled. Swordfish, Magma Golem, and Polar Bear all give +10% melee. Polar Bear is the teaching point: it matches the rare melee pets on paper and drops as a common Ice roll, so Ice can be a smarter Pearl spend than chasing Magma Golem only for damage.

Octopus sits here as the materials automation pick. It is not unique wipe insurance like Snowman, and it is not loot pickup like Salamander, but the 120-second materials loop is hard to replace and costs only 80 Pearls from Warrior. Arctic Wolf is the sprint cap for island hopping and kite routes.

B Tier

Image	Companion	Role	Buff	Chest / cost	Why it ranks
	Shark	Melee Damage	+7.5% melee damage	Fisherman's or Warrior / 40-80 Pearls	Solid melee until a +10% pet
	Dolphin	Sprint	+7.5% sprint speed	Fisherman's or Magma / 40-120 Pearls	Strong early sprint; also Magma
	Whale	Health	+7.5% health	Pirate / 120 Pearls	Mid health bump while waiting on better roles
	Parrot	Gun Damage	+7.5% gun damage	Pirate / 120 Pearls	Gun filler until Pirate Gunner
	Lava Snail	Hunger	7.5% less hungry	Magma / 120 Pearls	Better hunger % than Frog
	Orca	Health	+7.5% health	Ice / 120 Pearls	Health buff, same tier as Whale

B Tier covers the +7.5% combat, sprint, health, and hunger pets. They are fine while you wait on S or A roles, and Shark or Dolphin are especially useful early because they can appear from cheaper chests.

Orca is health +7.5%, not sprint. Use it like Whale for durability until Snowman, Penguin, or a stronger combat buff shows up. Lava Snail beats Frog on hunger percent, but Crow or Seagull usually fix food better by delivering meals.

C Tier

Image	Companion	Role	Buff	Chest / cost	Why it ranks
	Turtle	Health	+5% health	Fisherman's / 40 Pearls	Cheap early health
	Snorf	Health	+5% health	Warrior / 80 Pearls	Same +5% health as Turtle
	Cat	Sprint	+5% sprint speed	Warrior / 80 Pearls	Small sprint bump
	Crab	Gun Damage	+5% gun damage	Fisherman's / 40 Pearls	Tiny gun bump for early ranged

C Tier pets are Fisherman's and Warrior fillers. Keep them while Pearls are scarce, then replace with any matching B or higher buff. Turtle and Crab are fine first rolls from the 40-Pearl chest. Cat and Snorf are the same idea at 80 Pearls: usable, not a long-term target.

D Tier

Image	Companion	Role	Buff	Chest / cost	Why it ranks
	Frog	Hunger	5% less hungry	Fisherman's / 40 Pearls	Weakest long-term hunger option

Frog is fine for one early Fisherman's roll, then it ages out fast. Lava Snail is a stronger hunger percent, and Crow or Seagull usually fix food better by delivering meals on a timer.

Spend Pearls in order: Fisherman's for cheap fillers, Warrior for Shark, Swordfish, or Octopus, then the 120-Pearl chest that matches the role you still lack. Pair the companion with your class plan, and use the 100 Days At Sea wiki when you need the wider loop around islands and bosses.
