Tile skull

Is there any way to change the tile skull skin?

 

You can use one of the default ones(Zombie head, Skeleton head, Steve head, etc.), but custom skulls are not yet supported by MCPE.

 

haa ok, thanks.

 

You can always try making a texture pack if you want a custom head

 

Is it possible to spawn a human and make everything except the head transparent?

 

If the skin is correctly made, yes, but the head will appear floating

 

Spawn it into the earth then, or will it suffocate?

 

Not if you change $entity->canCollide to false.
