"Fungus and a sea crab. One sought a host; the other, a new home."

Crabulon is a Pre-Hardmode boss, intended to be fought after the Eye of Cthulhu.

Spawn

Crabulon does not spawn naturally and the player is required to summon it by using the Decapodita Sprout in the Glowing Mushroom biome at any time.

Behavior

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 towards the player. Crabulon will stay in its walking phase for a shorter time if it gets hit or the player is too close to it.

Crabulon will enrage if the player is 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 fires 1 Mushroom Shot at the player, which is affected by gravity.
• Mushroom shots start out translucent when fired and will not deal damage until they start falling, indicated by a round flash of particles. (This also applies to the falling mushrooms in higher difficulties)
• After 6 seconds of idling, it repeatedly slams its claws around. During this animation, it jumps towards the player 3 times, each with a 5-second delay.
• When 5% of its health is lost, the resulting hit launches 2 / 3 / 4 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 jump through solid tiles.
• Stays in its walking phase for an even shorter time when getting hit or the player is too close to it.
• When at 66% health:
  • The number of mushroom shots fired increased to 3.
  • Fires mushroom shots 33.33% faster.
  • Increases horizontal and projectile speed.
  • Reduces the delay between jumps by 80%.
  • Jumps 4 times instead of 3.
• When at 33% health:
  • The number of mushroom shots fired increased to 6.
  • Fires mushroom shots 40% faster.
  • Increases horizontal and projectile speed.
  • Reduces the delay between jumps by 40%.
  • Fires a spread of 20 Falling Mushrooms on every other jump.

In Revengeance Mode

• Spawns 3 Crab Shrooms instead of 2.
• Fires a large and random spread of 11 / 15 falling mushrooms into the air as Crabulon lands its final jump in each sequence.
  • When at 66% health, it instead fires 20 / 24 falling mushrooms every other jump.
• Crabulon's jumps scale in height based on vertical distance from the player and attempts to intercept them if they are moving.
• Upwards speed, vertical acceleration, and fall speed while moving through tiles is increased.
• 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.
• Crab Shrooms have a 25% higher terminal fall speed and faster horizontal and slower vertical velocity.
• Mushroom shots are fired at a faster rate.

In Death Mode

• Spawns 4 Crab Shrooms instead of 3.
• Idles for less time as its health lowers, up to 2 seconds less.
• Moves even faster as its health lowers.
• Upwards speed, vertical acceleration, and fall speed while moving through tiles is increased.
• Crab Shrooms have a faster horizontal and slower vertical velocity.
• Fires mushroom shots at a faster rate and they are fired lower and decelerate less.
• Has a higher horizontal while jumping and falls faster when directly above the player during a jump.
• The number of falling mushrooms and their velocity are increased.
• When at 66% health, it fires falling mushrooms on every jump.
• When at 33% health, its final jump fires even more falling mushrooms.

Resistances

• Crabulon takes 50% damage from true melee hits.

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 its 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, the player should move slowly during the falling mushroom wall attack to easily dodge them.
  • This attack always happens on its 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".
• 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 mycelial 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."
