Disney's Grandson Pleads Not Guilty 24 Times

Walt Disney's grandson pled not guilty to 24 felonies in Van Nuys Superior Court today -- which is officially the number of charges it takes to make DMX blush.

As we first reported, Patrick Disney Miller was arrested earlier this month after cops busted him for possession of ammunition ... a violation of his parole from a 2005 drug conviction.

Prosecutors tacked on 23 felonies yesterday -- including 19 counts of possession of a firearm by a felon, one count of possession of an illegal assault weapon and three counts of possession of a controlled substance with a firearm.

Miller -- who was free on $35,000 bail -- was taken into custody after the hearing and his bail was upped to $550,000.

He's due back in court on Feb. 4.
