Sir Dax

Sir Dax (also known as Sir Reginald Dexter Sircliff IV is a ghost who appears in the Sofia the First Halloween special, "Ghostly Gala".

Background
He is a ghost who lives in the castle attic along with his ghost bat friend Boo. Upon Halloween he invited all his ghostly friends and family to the castle for a Ghostly Gala but unfortunately Sofia's Halloween party was on the same night.

In order to have his Gala, he tried to scare everyone out of the castle as he believed they everyone would freak out if they saw his ghostly friends. Sofia kept interfering in his attempt to scare everyone but didn't realize that Sir Dax only gets to see his friends and family every one hundred years and if he doesn't get to do his Ghostly Gala he will not get to see them for another century.

Things soon went out of control when Sir Dax used bats to frighten everyone away. Although he succeeded he couldn't get rid of the bats. With help from Sofia he was able to scare them out of the castle and in gratitude for helping him, he decided they could have both their parties.

Sir Dax got his Ghostly Gala and Sofia got her Halloween party while every believed all of Sir Dax's ghostly friends were just Halloween tricks made by Sofia.
