You can't put the Muhammad dolls in the same room with the Hare Krishna and Buddha dolls or even a Barbie doll. Upon returning in the morning, shopkeepers have found those dolls beheaded. "I'm Muhammad; wanna' play?"
Back of package reads "CAUTION: YOUNG CHILDREN MAY LOSE BODY PARTS IF LEFT UNATTENDED WITH MUHAMMAD DOLL. IF MUHAMMAD DOLL BECOMES VIOLENT, HE MAY BE APPEASED BY REPEATING 'ALLAH IS GOD AND MUHMMAD IS HIS PROPHET' THREE TIMES AND BY PLACING THE MATTEL SUICIDE VEST (SOLD SEPARATELY) AROUND THE CHILD."
There's also evidently a design flaw as the Muhammad dolls tend to spontaneously burst into flames in the presence of a Jesus doll.
There's a safety feature...the child can submit to the will of Allah - or pay the muhammed doll a special tax.
