Jelly King

The Jelly King is a Boss mob that is found at the end of Jelly dungeons.

Appearance
The Jelly King is a giant, 7 1/2-block length 7 1/2-block height, tan-coloured slime which spawns in the final room of the Jelly dungeon. It also constantly emits Enchantment Table particles once awoken.

Dormant Stage
The Jelly King Spawns in the center of a large room, which has several low gaps in between tiles. In the first stage, or "dormant" stage, it appears in a gray-black colour and is immobile, though it does deal damage to anything that comes in contact with it. It awakens to the Secondary stage after being hit by a Sword.

Aggressive Stage
After being awoken, the Jelly King turns into and orange-tan colour, performing several different attacks.

Death
Once defeated, the Jelly King drops a Jelly boss key which unlocks the door to the final treasure room.

Attacks
Giant Leap

The Jelly King jumps to the roof of the room and back, resulting in damage and a lot of knockback.

Minion Call

The Jelly King spawns 1 of the 3 different Jelly mobs, aiding it in battle.

Explosive Leap

There is 1 in 4 chance that when the Jelly King lands on the floor after performing the Giant Leap attack, that a large explosion occurs, similar to the Jelly Queen.

(Note: Due to the blocks in the Jelly Dungeon being indestructible, the explosion will break no blocks on impact.)

Gummy Ball

The Jelly King randomly fires a Gummy Ball projectile which deals damage as well as the slowness effect when hit.

Other
Size Decrease

Every so many hits, the Jelly King reduces in size by 1/2 a block, ending up a Tiny size Jelly when almost dead, though it must be noted that the Jelly King does not re-spawn once killed, unlike the PEZ Jelly.

Jelly Boss Key
When the Boss is defeated, a Jelly Boss Key will drop as a result. It is used to open the Jelly King's Locks at the far end of the room and earn access into the Boss Loot Room.

Loot Chest
Inside the room, one will find a Loot Chest in the middle (Note: The Chest will not be exactly in the middle of the Room. It will be placed somewhere on the Room's middle platform). The Loot Chest contains several different items when opened, from the rarest to the most abundant!
