How to Unlock Companions

Companions are obtained by opening chests that you purchase with Pearls. Pearls are earned by completing daily quests and looting chests scattered across islands. Each chest has a fixed cost and a specific pool of companions with different drop rates. The four chest types are:

  • Fisherman’s Chest – 40 Pearls (common/rare mix)
  • Warrior Chest – 80 Pearls (common/rare/epic)
  • Pirate Chest – 120 Pearls (rare/epic)
  • Magma Chest – 120 Pearls (rare/epic)

Below are the detailed drop rates for each chest, compiled from in‑game data and community reports.

Rare Companions

Rare pets offer stronger buffs (7.5%–15% at max) and some have utility abilities that auto‑gather items.

Tip: Octopus and Seagull/Crow are excellent for farming – you can focus on combat or exploring while they bring you supplies.

Epic Companions

Epic pets are the top tier of permanent companions. They provide the highest stat buffs (10%–20%) and two of them have unique gathering abilities.

PetLevel 1 BuffMax Level BuffSource
Swordfish10% more melee damage20% more melee damageWarrior Chest / Pirate Chest (5%)
Pirate Gunner10% more gun damage20% more gun damagePirate Chest (5%)
SalamanderPicks up and delivers loot(same effect, likely improved range)Magma Chest (5%)
Magma Golem10% more melee damage20% more melee damageMagma Chest (5%)

The Salamander is a community favorite because it automatically collects loot from defeated enemies and delivers it to you – a huge time saver for clearing islands. The Magma Golem matches the Swordfish’s melee buff, making either one a strong choice for melee builds.

Legendary: Hydra

The Hydra is a limited‑time legendary companion. It does not come from a chest; it was available through a special event (and may return in future updates). The Hydra shoots fireballs at enemies, dealing damage over time. At max level the fireball damage increases, but the attack speed remains the same.

PetLevel 1 EffectMax Level Effect
HydraShoots fireballs at enemiesIncreased fireball damage

Note: The Hydra cannot be upgraded in the usual sense – its “max level” simply adds extra damage. According to community reports, it remains one of the strongest offensive companions when you can get it.

Shiny Companions

Every companion (except the Hydra) has a 1 in 100 chance to be a Shiny version. Shiny pets have a unique cosmetic appearance but exactly the same stats as the normal version. They are purely for bragging rights.

Best Companion for Your Playstyle

Choosing the right companion can dramatically improve your efficiency. Here are our recommendations based on common playstyles.

Melee Build

  • Primary: Swordfish or Magma Golem (20% melee damage at max)
  • Secondary: Shark (15% melee damage until you get an epic)
  • Utility: Octopus (gathers materials while you fight)

Ranged/Gunner Build

  • Primary: Pirate Gunner (20% gun damage at max)
  • Secondary: Parrot (15% gun damage) or Crab (10% gun damage)
  • Utility: Seagull or Crow (keeps your food topped up)

Survival / Farming Build

  • Primary: Whale (15% health) for survivability
  • Secondary: Frog or Lava Snail (reduce hunger drain)
  • Utility: Octopus (materials) + Salamander (loot pickup)

Speed Runner

  • Primary: Cat (10% sprint) or Dolphin (15% sprint)
  • Secondary: Any movement boost
  • Utility: Salamander or Octopus to keep your inventory clear

Pro tip: You can only have one companion active at a time, but you can switch between owned pets freely. Unlock multiple companions to adapt to different situations during a single run.

Tips for Maximizing Your Companions

  • Level them up quickly. Companion buffs double at max level, so focus on using your active companion to gain experience (combat and gathering contribute to leveling).
  • Open chests strategically. If you need a specific pet, target the chest with the highest drop chance. For example, the Warrior Chest gives a 32% chance for Snorf or Cat.
  • Save Pearls for Magma Chest. The Magma Chest offers some of the best utility pets (Salamander, Magma Golem) and also includes the Dolphin and Crow. It’s a great all‑round investment.
  • Don’t ignore common pets. Even a max‑level Frog or Crab can give you a noticeable edge early on, and they are easy to get.
  • The Hydra is temporary. If the Hydra event is active, grind for it – it’s the only companion that directly damages enemies without any input.
