Hello Atomization, This is something that PureEntititiesX can help you with, it is currently in a unstable state although it appears to be actively maintained. The plugins is currently located in a few places such as GitHub and Poggit. The issue tracker can be used to report issues with the currently unstable plugin.
This does not seem to exist at the moment @Atomization, to my knowledge you would need to work with animations, and mob spawning packets.
It’s has spawner atleast PureEntites: https://github.com/RevivalPMMP/PureEntitiesX TeaSpoon: https://github.com/CortexPE/TeaSpoon If u only want spawner than copy and paste teaspoon or PureEntities register the block and tiles
