Creeplex/Creeplexes (New Creeper Variant)

This is an idea for a new type of creeper. This can be a type of creeper that behaves like a normal creeper, it comes towards you and explodes. However, this kind of creeper won’t make a normal explosion, it will create an explosion where the explosion makes a plus shaped symbol. These creepers would grey with white eyes and you would find them in caves. They could also drop a special type of gunpowder that could be used to create a unique type of TNT that would make the same plus symbol explosion as the Creeplux.
