Everything Is Crab 100% Achievement Guide: Surviving The Grind

Before you pull your hair out trying to defeat a massive boss with a thrown rock, you need to understand the exact mechanics behind this brutal completion list.

Everything is Crab looks like a chaotic good time until you check the achievement list and realize the developers actively want you to suffer. The game expects you to clear pacifist runs, manipulate your physical size to absurd extremes, and somehow win 200 separate times. Some of these trophies will pop naturally while you learn the ropes and climb the difficulty ladder. Others demand incredibly specific, hyper-focused builds that will send you right back to the lobby if you make a single wrong mutation choice. I mapped out the exact requirements and strategies for every single achievement so you can actually hit that 100 percent mark without completely losing your sanity.

Progression And The Endless Grind

These are the achievements you will largely unlock just by suffering through the core game loop and pushing the Pressure levels.

You do not need crazy gimmicks for most of these, just raw persistence and a lot of free time. The 200 wins requirement is a massive slog, especially since Challenge runs do not count toward that total. You just have to grind standard runs until your eyes bleed. I put the baseline progression requirements in a clean table below so you know exactly what kind of time sink you are looking at.

Achievement Unlock Requirement & Strategy
Weeeee back! Complete the opening tutorial. You get this practically for free.
Picky Use DNA to reroll your evolution options 100 times across all of your runs.
Selective Pressure 1 & 20 Beat the first difficulty level, and then beat the absolute hardest Pressure 20 difficulty.
Extinction 5 Clear the Extinction 5 difficulty setting. Expect massive enemy scaling here.
Complete Complete a Pressure 20 run with all Genetics. A massive grind that requires deep game knowledge.
Win / Winner / Winnest Win 10, 50, and 200 runs. Challenges do not count toward this total.

Stat Manipulation And Specific Evolutions

The game wants you to push your genetic mutations to absolute extremes to secure these specific unlocks.

You cannot get these by playing normally. You have to commit to a gimmick from the very first level up. If you are going for The Crabtain, you have to strictly pick crab parts like the Pincer, Scuttle, Antennae, and Exoskeleton while actively avoiding traits like Fur or Fin. For the Frens achievement, you need to rely heavily on your Social stat to raise your ally cap while grabbing charm skills like Tail Wag and Toe Beans.

Achievement Unlock Requirement & Strategy
Chonkers Reach 200 percent Size. Use evolutions like Alpha, Chonky, and More Mass.
Dechonked Reach down to 40 percent Size. Stack the Elusive and Smol evolutions.
Dodgy Reach 75 percent Dodge. Grab Agile, Elusive, and More Eyes to become untouchable.
You Show Speed Reach Speed 12. Prioritize movement with Hollow Bones, Legs, and Sprint.
Frens Have 12 charmed allies at once. Boost your Social stat and use charm abilities like Tail Wag.
100 coats Use Moulting 10 times in a single run. Requires the Exoskeleton evolution to unlock.
The Crabtain Reach Carcinisation 10. Only pick crab evolutions and ignore things like scales or fur completely.

Damage Scaling And Pure Pacifism

This is where the achievement list gets genuinely sadistic. The developers expect you to deal hundreds of thousands of damage in some runs, and absolutely zero in others.

For the heavy damage numbers, you need to rely on the Pistol Pincer evolution combined with the Revenge trait. This creates a massive burst damage window that allows you to hit the 500 damage mark for the Ultrabonk trophy. On the flip side, the pacifist trophies require pure evasion or relying entirely on your charmed followers to do the dirty work. For the hilarious Not Even Yourself trophy, you just equip the Antlers trait and run around until you literally die to your own self-inflicted recoil damage.

Achievement Unlock Requirement & Strategy
Brute / Bruter / Brutest Deal 20,000, 35,000, and 50,000 total damage in a single run. High Pressure levels make this easier due to enemy health pools.
Ultrabonk Deal 500 damage in a single hit. Use the Pistol Pincer and stack Revenge charges before attacking.
Mountain Man Deal over 200 damage with a Stone. You absolutely must take the Stoner evolution for this.
Dove Win a run without dealing any damage. Rely heavily on a vegan build or charmed allies.
Can't touch this Complete a run without taking damage. Stack your Dodge stats and avoid greedy attacks.
Zen Beat a run without dealing nor taking damage. The ultimate pacifist test.
Not even yourself Die to your own damage to become your own Main Predator. Use the Antlers evolution to hurt yourself.

Boss Fight Executions

Defeating the bosses is hard enough, but doing it with these bizarre restrictions requires patience and a massive amount of burst damage.

The Crabtaur is going to be your best friend for these. You can earn an easy achievement just by hitting it while it charges, and another by baiting that same charge directly into a tree or obstacle. For Clawdia, you need to weaken her carefully and then charm one of her own Crawlee summons so it can steal the final hit.

Achievement Unlock Requirement & Strategy
Ole! Hit a Crabtaur while it is charging. Just drop a wide attack in its direct path.
Opportunistic Kill the Crabtaur by having it crash into an obstacle. Bait the red charge line into a tree.
In a rush+ Defeat a Boss in under 5 seconds. Use the Pistol Pincer burst setup to melt the health bar instantly.
Carcinise this Defeat the Final Boss in under 15 seconds. Again, the Pistol Pincer is your best option here.
Bullseye Kill a regular boss with a stone. Secure the Stoner evolution and land the final hit.
Rebellious Have a charmed Crawlee kill Clawdia. Charm her summons with Toe Beans and hope they get the final blow.
It was a dinosaur Have the Final Boss die to the Cataclysm Event. Weaken it and let the falling meteors finish the job.

Challenge Tiers And Collections

If you managed to survive the pacifist runs, you now have to deal with the Challenge mode and pure RNG collection logs.

The shiny creatures work exactly like Pokemon. They are differently colored, have sparkles around them, and appear completely randomly. You just have to play the game enough to witness 15 different variations. The true endgame test is fully finalizing every single challenge with every single Genetic. That alone will push your playtime into the hundreds of hours.

Achievement Unlock Requirement & Strategy
Challengedn't Beat all Challenges available in the game.
Gilded Finalize a Challenge by beating it with all Genetics. Look for the green check marks.
Really? Finalize all Challenges with all Genetics. Prepare for an incredibly long grind.
I wanna be the very best Defeat a single Shiny animal. Relies purely on luck.
I know it's my destiny Witness 5 different shiny enemies. You do not have to kill them, just see them.
Gotta catch them all Witness 15 different shiny enemies across your runs.
