When summoned, Crabulon initially remains idle and deals no damage, but it will start its normal behavior after 3.5 seconds or when attacked.
In its first phase, Crabulon alternates between two attacks:
Walk
- Crabulon walks towards the player, attempting to deal contact damage. Its walking speed increases slightly as it loses health.
Jump
- Crabulon comes to a stop, briefly lifts its arm, and jumps towards the player. The height and length of the jump scale with how far away the player is.
- Every third jump, upon landing, Crabulon fires a large ring of Spore Gas at random velocities. Spore Gas projectiles slowly decelerate, deal no damage for the first 2 seconds of their lives, and dissipate after 12 seconds.
