Okay, I went to Disneyland on Saturday as planned and bought one of the skulls. However, they were not being sold in the store with all the Indy merchandise. They were instead on the far side of the store right next door, situated among
Pirates of the Caribbean merchandise. So clearly these are more tied to that than
KOTCS since there were other pirate skulls nearby, including the larger "normal-looking" skull piggy banks someone else in the thread mentioned.
But still, they looked nice and are pretty heavy duty, so I bought one for $18. Here's a few pics. The third and fourth one I lit with a small flashlight just below camera frame to show how nicely it can light up.
My dad offered the suggestion of maybe building a small box to sit it atop of on a shelf, with a light in the box to light up the skull at nighttime, so we might explore that possibility soon. Made me start to wonder if the skull(s) in
KOTCS will light up as well.
