Basic
*Costume Prince will transform into a Slime King with increased size. Slime King explodes and spawns small slimes upon being hit.
Slime King can perform a fatal smash, jumping up and smashing the ground to poison an area and shoot out bullets.
Slime King will use Magic Gloves as his weapon.*
* Upon pressing the skill button, Costume Prince enters a mount that resembles Grand Slime. Taps on the skill button again to dismount:
	+ The mount has 25 health and cannot be healed in any way.
	+ It has a 0.4 seconds invincibility window upon getting hit.
	+ It has a larger hitbox, roughly 2.5 tiles diameter. Meaning that it cannot pass through narrower gaps.
	+ Costume Prince has movement speed reduced by 20% while using the mount, which is calculated after the Plant speed bonus (+1) and Magic Gloves speed bonus (+0.5 when using). The final speed value is (7 + 1 + 0.5)\*0.8 = 6.8.
	+ The player cannot pick up weapons while using the mount.
	+ The mount does not gain benefit from pet Robo's unique skill (which increase Armor mount health by 2).
* The mount cannot use any weapons. Instead, inbuilt Magic Gloves are used.
	+ This weapon function the same as the regular Magic Gloves aside from the energy cost, which is 2 instead of 4.
	+ The player cannot drop this weapon on the floor, Trash Can, Reforging Furnace, Resetting Furnace or Offering Pool.
* Every 2 hits the mount takes, it creates an explosion and summon a Slime (or Champion Slime if the player has Pet Buff).
	+ The explosion deals 10 damage and has a chance to inflict Burn.
	+ The Slimes are not affected by the  condition.
	+ The Slime will behave like those seen in the Knight Kingdom biome.
		- Small Slime has 12 health, deals 3 collision damage and explodes into 8 bullets each dealing 2 damage upon death.
		- Champion Slime has 50 health, deals 4 collision damage and explodes into 24 bullets each dealing 3 damage upon death.
	+ A maximum of 6 slimes can exist at the same time. Their lifetime is infinite; the only ways to make them despawn is either with their death or by deactivating the skill.
	+ When the skill is deactivated, each slime will instantly disappear in an explosion dealing 6 damage. This death effect does not trigger if the slime dies by any other means.
* While in the mount, taps the Extra Button  to can perform a fatal smash, jumping up and smashing the ground:
	+ Unlike Berserker's Leap, Costume Prince is vulnerable mid-air. However, he can still attack in mid-air.
	+ Upon landing, the mount creates a shockwave, a poison pool and releases numerous bubble bullets.
		- The shockwave deals 6 damage.
		- The poison pool deals 1 damage per tick and lasts for 5 seconds, it is generated centered on the shockwave.
		- Release 30 yellow bubble bullets dealing 3 damage each. The bullets quicky decelerate and disappear after 5 seconds.
	+ The shockwave and the bubble bullets have a hidden critical chance of 0.
	+ This ability has a cooldown of 1 second and takes about 2 seconds to deal damage.
* The skill's cooldown scales off the mount's current health: 2 seconds at full health, gradually scaling up to 12 (10) seconds when the mount is destroyed.
* Aside from the ones that normally affect Magic Gloves, other Buffs that affect this skill are the following:
	+ - Increases burn/poison status effect damage, increases the effectiveness of fire/poison pool spawned from various attacks.
	+ - All summoned slimes are converted into their Champion form, which have higher movement speed. Deactivating the mount will now cause the slimes to explode into bullets
	+ - Increases the number of bubble bullets summoned by the fatal smash attack by 14.
	+ - Expands the shockwave's AoE. Damage is unaffected.
	+ - Allows the shockwave to reflect bullets.
	+ - Neutralizes the fatal smash's cooldown.
	+ - These Buffs do not affect the fatal smash's bubble bullets.

Skill Upgrade
*Slime King can spawn more small slimes.*
* The number of slimes that can exist at the same time becomes infinite as long as the mount doesn't die.

Mentor Upgrade
*Whenever attacked, Slime King generates a small slime and leaves an ablaze area on the ground.*
* In addition to spawning a slime, the mount will generate a fire pool centered on it, dealing 2 damage per tick and lasting for 2 seconds.
* The fire pool is guaranteed to be enhanced by his passive buff, dealing 3 damage per tick and lasting for 5 seconds instead.

## Trivia

* This character was added in Update 5.4.0.
* The Costume Prince movement speed is slightly faster than other Characters, at 7.0. The vast majority of character's speed is 6.5.
* There's a bug in update 5.5.0 that reduces Costume Prince's Bare Hands damage to 4 from 6.
* The Slime King counts as a mount, therefore, it is not allowed when entering Rush to Purity.
* Before Update 5.4.5:
	+ The mount did not have an invincibility period upon being hit.
	+ The mount's HP was 40.
	+ The slimes summoned by the mount dealt 5 damage upon exploding.
	+ The bouncing attack had no cooldown.
	+ The first skill's cooldown was 8(10).
* During 5.4.0, several bugs occurred with Costume Prince's first skill:
	+ While being in the mount:
		- It will still take damage while Frozen.
		- Moonshine Frost Blade's cooldown will be halted until the player gets out of the mount.
		- Damage numbers when getting hit will not be displayed.
		- Milk does not affect it.
		- The skill has its own collision hitbox, meaning the player can trap other teammates in Multiplayer by blocking them in one spot.
		- Fertilizer can still be picked up and used normally, both as a weapon and as a gardening tool.
		- The Magic Gloves used by the skill can be dropped in the Offering Pool. This results in the skill's weapon switching to whatever weapon the player is currently wielding instead. This goes for all subsequent skill activations, and the Magic Gloves reappear only after moving to the next level.
		- Enemy projectiles that remain stuck on the character after hitting them (e.g. arrows) do not disappear after deactivating the skill. They will instead linger around the mount's previously larger hitbox, appearing as if they were hovering around the character.
		- In The Origin, its hitbox will collide with the Magic Stone's barrier, through which the player can normally pass.
			* The character's sprite is also missing from the interactive map, leaving a blank square instead.
