Minecart with Monster Spawner

The minecart with monster spawner is a combination of a minecart and a monster spawner.

Minecarts with monster spawner cannot be obtained as an item in the inventory, and can only be produced using the /summon command or by using external tools.

The monster spawner within the minecart behaves the same way as normal monster spawners, but the entity to be spawned cannot be set via using spawn eggs; the monster spawner's data can only be modified using commands or NBT edits. It has the same associated NBT tags as a normal monster spawner.[1]
