Queen Slime spawns above the player and attempts to slam downwards onto them. It cycles through the following attacks consecutively:
Crystal Leap
- Queen Slime leaps over the player, leaving behind a trail of crystals in its path.
- It then files directly above the player and attempts to slam onto them.
- As Queen Slime slams downwards, the crystals fall vertically downwards towards the ground.
- The crystals can also fly vertically upwards, depending on the position of the player relative to them.
Laser Maze
- Several static crystals form around the player's position along with 4 glowing crystals that appear by spinning around the player.
- The 4 glowing crystals briefly aim at the player's position, telegraphed by a series of blue lines, before firing lasers along the path.
- After firing the lasers, the 4 glowing crystals shatter.
- This attack is repeated 4 times before moving on to the next one.
Crown Bursts
- Queen Slime flutters above the player as its crown flies off and begins shooting at the player.
- The boss fires a spread of gel blobs which rain down around the player.
- Meanwhile, the crown rotates about the player, firing bursts of 5 Jewel Bolts at them.
- After this attack ends, the crown returns to Queen Slime.
Gelitic Army
- Queen Slime flies above the player and summons an army of slime minions near it before falling downwards simultaneously.
- These slime minions are randomly selected from one of two types:
Crystal Slimes
- On colliding with the ground, each Crystal Slime bursts into a set of 5 shards; 2 of which spread horizontally in either direction and 3 of which spread out upwards.
Bouncy Slimes
- On colliding with the ground each Bouncy Slime bounces back up until it collides with the ground again, after which it bursts and dissipates into nothingness.
- Queen Slime summons two waves of slime minions before moving on to the next attack.
