Considering he didn't move an inch while Anita was hugging him long after Cruella had left, this troper always took it to mean he had passed out from terror. Who could blame him?
The Twilight Bark sequence, and not just because we get to see cameos of all our favorite dog characters from Lady and the Tramp.
Sergeant Tibbs. EVERYTHING about him, but particularly noteworthy is that when Jasper is standing over the cornered pups, he spreads his front paws in front of them, shielding them despite being absolutely terrified. Fortunately, Pongo and Perdita burst in at the last second to stop the hoods.
Plus the Captain and the Colonel's final scene where the Colonel promises to hold Jasper and Horace of and the Captain giving the crooks a firm kick in the pants!
The collie that runs after the Pongos to get them out of the storm, which absolutely saved their lives. The dogs of the countryside had apparently set up a 24-hour watch, specifically for the purpose of helping the dalmatian caravan get home safely, and the Collie's appearance and reassuring voice was just an overwhelming rush of relief.
Patch's London Adventure
The Twilight Bark makes a triumphant return and helps save the puppies (again).
Patch tying up Cruella and saving Rolly, in almost the exact same way Thunderbolt did to the villain in his film near the beginning of the movie. Tying her up with her makeshift wipe and catapulting himself and Rolly back onto the Double Decker bus.
Unlike the Karma Houdini Cruella, Horace and Jasper pulled in the first film (other than Cruella being put on probation and the boys spending a few nights in jail because of the wreck) they are all arrested by the police in the sequel. Best of all Nanny got to witness this, no doubt very satisfying after what Jasper and Horace pulled earlier.
Cruella: You are a Control Freak! You're as cuddly as a gargoyle and you have the fashion sense of a DRUID!
She also looks Malevola's psychotic guard dogs straight in the eyes and says, without blinking, "YOU CAN BE FIXED."
Cadpig has a notable moment in "My Fair Moochie" when she beats the ever-living crap out of El Diablo, an unmovable Chihuahua who had casually flicked everyone else out of the ring.
Aside from all of her Pullet Marlow moments, Spot has an epic on in "Full Metal Pullet" when she stands up to Lt. Pug after he constantly berates and insults her and gives him an amazing "The Reason You Suck" Speech in the process.
