HALL 9000 is the thirty-eighth blooper created by SMG4. In this video, Mario installs a security system to prevent robbers from stealing things in Peach's Castle, but the security revolts against Mario and SMG4, locking them out of the castle.
Mario decides to get a security system for the castle, but the system turns on him, and now the castle is out of control.
The video starts with Toad in his corner (as always), Mario and a robber. When Mario installs security in the castle, SMG4 decides to visit. HALL 9000, the computer, thinks he is an intruder and tries to kill him. When HALL realized SMG4 was Mario's friend, it kicked him out. Mario, SMG4, and X decide to stop HALL 9000.
