I found this mob skin here> and thought about if this could be a great feature to The End. This is a pack that replaces the Slime mob with Magic Cube mob. Magic Cubes are supposed to spread magic on the ground, I don't know how it didn't work. Magic Cubes are also immune to potion effects. Magic Cubes drops Magic Cream at the same rate as Magma Cream. The Magic Cream item is crafted the same as magma cream but with the blaze powder being chorus fruit. Magic cream can be crafted into magic blocks which entities are applied the same effect as the spread from magic cubes when they are on it. Magic cubes will spawn: [​rarely in swamps, in end midlands, highly in end highlands]. This pack also lowers the spawning of endermen in the biomes where magic cubes spawn in.
