Programming Minecraft falling pee men from the sky?

I saw that at Abgeieft, where, with the help of a command, he dropped a lot of such Pipi men from the sky.

How do I do the wtf xD

Clear,

p.getWorld (). SpawnFallingBlock (loc, data);

is save, but how does it work with get.X () and get.Y ()?

You could change the texture of an anvil to fit "your purpose"

The emphasis is on "could"
