A dear friend of one of my cousin's former cellmates had something similar happen to them at DisneyWorld. They were at the meet and greet getting Bugs Bunny's autograph outside the liquor store on Main Street in AK. His wife looked away for just a second to change the film in her camera, and when she looked up again her 2 year old was gone!
They looked all over, security wasn't any help (you know how crime-ridden DW is), but finally at the end of the day she found the child, strapped to the front of an
ECV like a hood ornament. The lady was on her way out of the park and they caught her just in time.
It turned out the the lady on the ECV had done a fast drive by, grabbed the kid, and then zoomed off before anyone noticed. She then injected the kid with a concoction made from Dole Pineapple Whip and bat guano which made the child go to sleep. Then she painted the kid red, shaved his head, put MM ears on it and tied it to the front of her ECV. Everybody who saw it thought it was a decoration, except for the mom, who recognized the kid's Disney Crocs.
