Mob Spawn Eggs

I am trying to create a shapeless crafting recipe in which you put in a mob drop and an egg, and you get that mob's spawn egg. For example, I am trying to create a recipe for the creeper. Everything works, I can switch the output to anything and it works. But I just don't know the ID I need to put in for the output to get a creeper spawn egg. Here is my code:

ShapelessRecipe creeper = new ShapelessRecipe(new ItemStack(Material.MONSTER_EGG)).addIngredient(Material.EGG).addIngredient(Material.SULPHUR);

 

Code:java

ShapelessRecipe creeper = new ShapelessRecipe(new ItemStack(Material.MONSTER_EGG, 1, (short) 50)).addIngredient(Material.EGG).addIngredient(Material.SULPHUR);

Added the damage value 50 to the ItemStack constructor

 

Thanks
