Crabulon is a Pre-Hardmode boss. It is a giant, gray, fungus-covered crab with several glowing mushrooms attached to it.
Spawn
Crabulon is summoned by using the Decapodita Sprout in a Glowing Mushroom biome.
Behavior
When spawned, Crabulon will be passive towards the player, staying completely still and dealing no contact damage. While Crabulon is passive, the player is granted the Mushy buff, increasing defense by 6 and life regen by 2. It will become hostile if the player attacks it.
Once hostile, Crabulon will begin walking around and jumping at the player, all while firing a series of mushroom projectiles. It also starts summoning small Crab Shroom minions that slowly float downward while drifting toward the player.
Crabulon enrages outside the Glowing Mushroom biome or on the Surface, increasing its running speed. The enrage is even more effective if both conditions are met.
Attacks
- Every 5.375 seconds while idling, Crabulon launches one
Mushroom Shot at the player, which is affected by gravity.
- After 6 seconds of idling, it repeatedly slams its claws around. During this animation, it jumps toward the player three times, each with a five-second delay.
- When 5% of its health is lost, the resulting hit launches 2 / 2-3
/ 3
Crab Shrooms upwards.
- Crab Shrooms drift back and forth around the player and have a constant falling acceleration.
In Expert Mode
- Gains the ability to leap through solid tiles.

- The number of Mushroom Shots increases from one to three
- Fires Mushroom Shots 33.33% faster

- When below 33% health:

In Revengeance Mode

/ 15
Falling Mushrooms into the air as Crabulon lands its final jump in each sequence.
- Crabulon's jumps scale in height based on vertical distance from the player and attempts to intercept them if they are moving.
- Each jump varies in length and delay.
- The first jump is normal in length and delay.
- The second jump is higher with a slightly shorter delay.
- The third jump is lower with a very short delay.
- The fourth jump is lower but longer with an extremely short delay.

Notes
- If Crabulon is stuck and cannot get to the player, it can swim through blocks, similarly to the Mourning Wood and Everscream.
- The effects that Crabulon makes in the Get fixed boi secret world seed can cause ill effects in real life to people with flashing lights/motion sickness problems.
Tips
- For more elaborate strategies on defeating Crabulon, including weapon and arena recommendations, see Guide:Crabulon strategies.
- Stay underground when summoning the boss, as going to the surface will cause Crabulon to enrage, even if the player is in the Glowing Mushroom biome.
- The player should stay above Crabulon, as its stomp attacks deal a lot of damage. However, be wary of Crabulon's other attacks, like its exploding mushrooms and Crab Shrooms.
- Avoid staying directly above Crabulon as many projectiles come from it and go upwards.
- Although Crabulon can be fought as the first boss, be careful, as the boss can easily overwhelm an unprepared player.
- In Revengeance and Death Mode, move slowly during Crabulon's falling mushroom wall attack to easily dodge them.
- This attack always happens on Crabulon's 3rd jump.
Trivia
- Crabulon's theme is 1NF3$+@+!0N, which was composed by the artist DM DOKURO.
- When 1NF3$+@+!0N is played through a vectorscope, portions of the song create shapes that resemble mushrooms.
- The theme's name reads "Infestation".
- If the Calamity Music add-on mod is disabled, Boss 4 will play instead.
- Crabulon can be fought before any boss is defeated, as its summoning item only requires Glowing Mushrooms.
- Crabulon is often referred to as "The Perfect One" in the player base in reference to its former lore where it was given the title.
- If the Boss Checklist Mod is installed, its unique despawn message will be "The monstrous myclelial crab shuffles away..."
- The
Bestiary entry for the Crabulon: "A crustacean that once made its home in the heart of the Ilmeran Sea, managing to escape during the Great Incineration. Crabulon fled underground, enjoying the familiar blue glow given off by glowing mushrooms. Though it succumbed to the spores, it died in peace, reminded of its home."
