Sava-O Screaming Baby Skull Whistle

Get your stocking stuffers early:

The Sava-O is an innocent whistle trapped in the plastic prison of a scary, devil-spawn baby. When brave users blow into the device, the baby's head pops up and its mouth opens, shrieking/cursing your enemies through the power of your lungs/the genetic modification of Satan's DNA.
