The new "Casper" broke from earlier versions, following a sitcom-style pattern of one-liners and pop culture gags in a manner similar to the "Casper" feature. The show would also frequently break the fourth wall. The show used old "Casper" supporting characters such as Casper's cousin Spooky, Spooky's "ghoulfriend" Pearl (or "Poil" as rendered by Spooky's Brooklyn accent), and Nightmare the Ghost Horse who, unlike in the original cartoons and comics, does not actually talk (though voiced by Frank Welker). The show also introduced new characters, including Casper's super-loud teacher Ms. Banshee.
