I have looked everywhere I know to look but can't find this minifigure head listed. Any help appreciated.
I talked to a Lego expert on the lego.com online chat. He told me that this particular lego head was an exclusive part for the Build a Minifigure bin and gave me the part number for it 6257472 mini figure head #2829. I didn't know there were exclusive parts in the minifigure bin, I wonder if this is something new. He seemed quite surprised when he found it in the lego database as being exclusive to the build a minifigure bin.
Found it on brick link Catalog: Parts: Minifigure, Head: 3626cpb2325.
Title says it's a Minifigure, Head Mime Smiling Face, Black Star Eyes with White Pupils Pattern - Hollow Stud
