Prison Slimes are a rare mob that originates from Minecraft: Story Mode.
Spawning[]
Item[]
Prison Slimes do not spawn naturally and can only be spawned by players using their fused item, which can be crafted with an Egg, one Slimeball, and one block of Iron Bars. It takes a total of 32 seconds for the fusion part to be fused, at the cost of 12 mana. After which, you'll have your spawn item to spawn a Prison Slime, which will spawn in at a random size.
Behavior[]
Prison Slimes attack similarly to both the normal Slime and the Magma Cube, which is by leaping into opponents to damage them, however they do have a unique ability that those mobs lack; They are able to inflict Slowness onto their opponents, which lasts four seconds on Easy, nine seconds on Normal, and 24 seconds on Hard. The tier of Slowness also depends on the difficulty, with it inflicting Slowness II on Easy, Slowness III on Normal, and Slowness IV on Hard. Due to the ability to inflict Slowness, these are usually the best Slime version to use, and the Big versions are the best for their highest health and damage output, while the Small versions are useless due to fact any attack in the game can kill them.
The player is able to mount a Medium or Big Prison Slime and ride on it, however, they cannot move normally and can only move by holding the jump button to make them leap, however they are not as good at jumping compared to Magma Cubes. When a Medium or Big Prison Slime dies, it will split into 2-4 Medium or Small Prison Slime respectively. Engender Prison Slimes lack a female model, however, they will still have female names and still make the female mob sounds when attacked, which is most likely as a result of them using the same data as the Slime. Unlike their canon counterparts, you cannot bounce off of an Engender Prison Slime. There is currently a bug where if you turn on the female models and then turn it off while you have a Slime, Prison Slime, or Magma Cube Girl out, the game will crash, which is most likely due to the face that the normal mobs have a different way of moving compared to the female models. If an Engender Prison Slime is made into a Hero Prison Slime via use of The Star of Valor, it will gain a new attack where it will occasionally create an explosion that damages all enemies within the current chunk, even those that are underground.
