Everything is Crab 100% Achievement Guide & Bestiary

At first glance, Everything is Crab looks like pure chaos with weird creatures, absurd builds, and nonstop mutations everywhere on screen. Then you check the achievement list and suddenly realize the game actually expects you to survive impossible challenge runs, avoid all damage, defeat bosses in ridiculous ways, and somehow turn yourself into the ultimate crab lifeform.

Some achievements unlock naturally just from playing, but others are extremely specific and can feel confusing without knowing the proper setup beforehand. If you are trying to fully complete the game, this guide breaks down every achievement along with the easiest methods, useful builds, and a few tricks that make the grind less painful.

Everything is Crab 100% Achievement Guide

These are the easiest achievements in the game and mostly unlock naturally early on.

Weeeee Back!

Complete the tutorial.

You will unlock this immediately after finishing the opening tutorial section.

Size, Speed, and Dodge Achievements

A lot of achievements in Everything is Crab revolve around building your stats to extreme levels during a run.

Chonkers

Reach 200% Size.

To unlock this, focus heavily on bulky mutations and upgrades that increase overall body mass. Tank-style builds naturally gain size very quickly.

Dechonked

Reach 40% Size.

This achievement works the opposite way. Avoid size increases entirely and prioritize lightweight or mobility-focused evolutions whenever possible.

Smaller builds are surprisingly strong because dodging becomes much easier.

Dodgy

Reach 75% Dodge.

This is easiest with fast evasive builds. Stack dodge upgrades early and avoid mutations that trade agility for defense.

Once your dodge gets high enough, enemies start missing constantly.

You Show Speed

Reach Speed 12 during a run.

Speed-focused builds become incredibly fun once they start snowballing. Prioritize movement upgrades whenever available and avoid heavy defensive mutations slowing you down.

Damage-Based Achievements

These achievements require huge amounts of damage output during a single run.

Brute

Deal 20,000 total damage.

Bruter

Deal 35,000 total damage.

Brutest

Deal 50,000 total damage.

You will usually unlock these naturally while attempting higher difficulty clears. Long runs with strong scaling builds make these much easier.

Fast attack evolutions and area damage upgrades help a lot.

Ultrabonk

Deal 500 damage in a single hit.

Heavy burst builds are best here. Focus entirely on raw damage scaling instead of attack speed.

Critical-hit mutations can also make this achievement far easier than expected.

Mountain Man

Deal over 200 damage using a stone.

You specifically need the Stoner evolution for this achievement.

After unlocking it, stack damage upgrades before throwing rocks at enemies or bosses.

No Damage and Pacifist Achievements

These are some of the most difficult achievements in the game because they require very controlled runs.

Dove

Win without dealing damage.

The safest strategy is using passive builds that rely on charmed allies or environmental effects instead of direct attacks.

Accidentally damaging even a single enemy can ruin the achievement, so play carefully.

Can’t Touch This

Finish a run without taking damage.

Movement and dodge become extremely important here.

Do not play aggressively. Surviving safely matters much more than killing enemies quickly.

Zen

Complete a run without dealing or taking damage.

This achievement is honestly brutal.

You essentially need:

  • No incoming damage
  • No outgoing damage
  • Enemies dying indirectly

Most successful runs depend heavily on good RNG and very specific builds.

Not Even Yourself

Become your own Main Predator.

You must die from self-inflicted damage.

Using Antlers while your health is low is usually the easiest method.

Evolution Achievements

These achievements require building toward certain mutation paths.

Frens

Have 12 charmed allies at once.

Charm-based evolutions are required for this one. Continue charming enemies until your army reaches twelve active allies simultaneously.

The screen becomes complete chaos afterward.

The Crabtain

Reach Carcinisation 10.

To unlock this, commit fully to crab evolutions throughout your run.

Helpful upgrades include:

  • Pincer
  • Pistol Pincer
  • Scuttle
  • More Legs!
  • Shell
  • Antennae
  • Molting

Basically, evolve into the most crab-like creature possible.

100 Coats

Use Molting 10 times in one run.

Longer runs make this much easier since Molting can trigger repeatedly over time.

Victory Achievements

These track your progression through higher difficulties and repeated wins.

Selective Pressure 1

Beat Pressure 1.

A straightforward early-game achievement.

Selective Pressure 20

Beat Pressure 20.

This is where difficulty spikes massively. Enemies become extremely dangerous and weak builds fall apart quickly.

Dodge-heavy or summon-focused builds tend to perform best here.

Complete

Beat Pressure 20 with every Genetic.

One of the largest grinds in the game.

Since Genetics completely change gameplay, some clears feel dramatically harder than others.

Extinction 5

Clear Extinction 5 difficulty.

Expect intense enemy scaling and much longer survival requirements.

Win

Win 10 runs.

Winner

Win 50 runs.

Winnest

Win 200 runs.

The 200-win achievement especially takes a very long time unless you play consistently.

Challenge Completion Achievements

Challengedn’t

Beat every challenge mode.

Some challenges are simple while others completely change how the game plays.

Gilded

Finalize a challenge by beating it using every Genetic.

Every completed Genetic places a green checkmark beside the challenge.

You must fill all of them.

Really?

Finalize every challenge using all Genetics.

This is probably one of the hardest achievements currently in the game simply because of the amount of repetition involved.

Definitely intended for completionists.

Boss Achievements

Several achievements revolve around defeating bosses in unusual ways.

Ole!

Hit a Crabtaur while it charges.

Time your attack during the boss charge animation.

Opportunistic

Kill the Crabtaur using an obstacle.

Lower its health first, then bait the charge attack into a tree or cactus.

This achievement is honestly pretty funny once it works.

In a Rush+

Kill a boss in under 5 seconds.

Save burst abilities and cooldowns specifically for boss fights.

High-damage builds make this much easier.

Bullseye

Kill a boss with a stone.

Using the Stoner evolution, land the final hit using a thrown rock.

Rebellious

Have a charmed Crawlee kill Clawdia.

During the Clawdia fight:

  1. Charm one of the Crawlees.
  2. Lower Clawdia carefully.
  3. Let the charmed ally finish the boss.

This one can take several attempts because combat becomes messy quickly.

It Was a Dinosaur

Have the Final Boss die from the Cataclysm Event.

During the final fight, meteors eventually begin raining from the sky.

You must weaken the boss enough so meteor damage finishes it instead of your attacks.

Shiny Creature Achievements

These achievements mostly depend on luck.

I Wanna Be the Very Best

Defeat a shiny creature.

I Know It’s My Destiny

Find 5 different shiny enemies.

Gotta Catch Them All

Find 15 different shiny enemies.

Since shiny encounters are random, these achievements mostly unlock naturally over time.

Some players get lucky quickly while others may need dozens of runs.

Bestiary and Completion Achievements

Full Cast

Unlock every Genetic.

Most Genetics unlock naturally while progressing through challenges and higher difficulties.

Full House

Complete the Bestiary.

You must discover:

  • Standard creatures
  • Evolution variants
  • Bosses
  • Boss summons

Many players miss summon entries during boss encounters, so keep an eye out during fights.

Trying to 100% Everything is Crab becomes much harder than most players initially expect. Some achievements are simple progression milestones, but others require extremely precise runs, strange build setups, or pure luck.
