From October 23, 2009 thru Nov 1, 2009, and "enhanced" version of Halloween Screams appeared at the Rivers of America at Disneyland in California. The mist screens display the video that could be seen on the inflatable balloon next to Sleeping Beauty Castle.
There are slight differences though between the Castle and the River Mist. The inflatable balloon next to the Castle displays Dalmatian spots during the Cruella De Vil segment, but does not display on the mist screens. The A-E-I-O-U segment has two eyes displayed on the mist screens while there is only one eye shown on the inflatable balloon
