Heads don't drop as items from Creepers, Skeletons, and Zombies

Not a bug, they're just rare

It'd be fine if they were rare. They're impossible to obtain in Survival.

Are they even meant to? I know wither skeleton heads do but I have yet to witness any of the others. If so I guess that's intended.

What good reason could they have for making Wither Skeleton heads drop from Wither Skeletons, but not having Creeper, Skeleton, and Zombie heads drop from their respective mobs?

What reason could there be for adding various slabs not not nether brick slabs? Its the same thing. Its intentionally not added, why I cannot answer.

These are decorative blocks only, apart from the wither skeleton head which actually has some use to create a wither. As such they are not supposed to drop their heads. Closing as it works as intended.

So... bad game development then? 😛

I wouldn't put it passed Mojang to just... forget to toggle them. 😛 They do development like a 10 year old ADHD kid who refuses to take his Ritalin. "I'm going to make Lecterns. Oh wait. I'm going to ride my bicycle."

It's bad game development because they rolled out effectively 1/4 of a feature. This kind of thing would be acceptable if the game were in Beta, but since it's supposed to be a "released" product, there being features that are half-rolled out just makes the development cycle seem sloppy and apathetic.

It's impossible to obtain those Heads, at least you have TooManyItems or NotEnoughItems or commands /give or Creative.
So this is not a bug, only a old feature.

well i was just looking at these to see what they were ... i noticed some people were still watching: you can only get mob heads other that wither by charged creepers.
