Unmarked spoilers! You Have Been Warned!
Film

The best musical number in animated history!
As much as the last movie had many targeting moments, this movie's stakes are much higher with being an Actionized Sequel and focusing on a mystery-related premise.- The opening fight with Sherlock and Moriarty.
- Sherlock: This stops now, Moriarty!
Moriarty: Oh, be honest, Sherlock, you enjoy our little game as much as I do.
Sherlock: This is no game! I am the sworn protector of London's garden gnomes.
Moriarty: If you're the sworn protector of the city's gnomes, then I am their sworn destroyer! [kicks off a piece of a dinosaur fossil which shatters a gnome's hat] And we will keep playing this little game, Sherlock, until I crush every last gnome in London!
Sherlock: I'll stop you until the day I die!
Moriarty: Oh, lightbulb moment, what is it? Yeah! [jumping close] Today's that day! Come, Sherlock, come dance with me!
- They commence their fight in a sword fight-esque way, with Moriarty tripping Sherlock, making him hold on for dear life. Fortunately, when Moriarty was about to hit him, he misses and Sherlock pulls Moriarty's rolling pin down with Moriarty alongside it, having the pie mascot plummet down to the ground, along with accidentally hitting the lift on the dinosaur fossil upon impact, with the fossil toppling down on him.
- Watson tosses Sherlock his cane and the latter uses its grapple ability to get to safety before joining Moriarty's demise.
- Gnomeo gears up to get the Cupid's Arrow Orchid for the garden.
- Gnomeo, Juliet, Sherlock and Watson riding the waves on Sherlock and Watson's boat.
- This movie features two chase scenes:
- The Maneki-neko cats give chase on the main gnomes after Gnomeo accidentally shoves one of them into the Empress, tipping her over. They evade the cats with Chinese lanterns and suction cups, followed by jumping off the top of the Chinese emporium and land on a moving bus.
- Another has Juliet and Sherlock in a squirrel disguise evading a pug in a park after accidentally waking it up from retrieving the clue. During the chase, they start going in different directions, then ride in a rideable lawnmower. Not afterwards crashing in a tree from unintentionally jumping a row of lawn chairs propped up as ramps.
- However, this could also fall in the funny category.
- In the doll museum:
- Irene, whose a doll, pulls the arm off a mechanical gorilla. Not bad, for a doll.Big Boy Gorilla: Aw, my favorite arm!
- Irene's musical number "Stronger Than I Ever Was
" (pictured above) is something to give Disney a run for its money.
- Her whole song is about how she became independent and no longer gave a rat's ass about Sherlock anymore.
- Irene, whose a doll, pulls the arm off a mechanical gorilla. Not bad, for a doll.
- Moriarty, who was presumed "deaded", had survived his demise. Upon revealing his faked death, he explains his well though-out plan in smashing the gnomes and by manipulating Watson in convincing him on his side and getting his help in kidnapping the gnomes. And after doing so, he'd placed them under the London bridge with the bridge rising for the HMS Nimrod (which the main heroes are on), and will frame Sherlock as the one responsible.
- The climax:
- Gnomeo and Juliet vs. the gargoyle henchmen.
- Gnomeo jumping off the bridge.Ronnie: What'a you doin'?
Gnomeo: Jumpin', of course. (jumps off)
(glancing down, the gargoyle duo sees that he'd landed on the drone Juliet is piloting) - Gnomeo and Juliet deal with the gargoyles by having them be spotted by a patrol boat. As the searchlight shines upon them, they freeze and end up falling into the water.Gnomeo: Two gargoyles against two garden gnomes?
Juliet: We're Gnomeo and Juliet. They didn't stand a chance!
- Gnomeo jumping off the bridge.
- Sherlock and Moriarty's final battle.
- Moriarty uses one of the pieces of the fireworks' display, courtesy of the gargoyles, as a cannon-blaster on Sherlock.
- Sherlock, with an injured leg, charges at Moriarty, sacrificing his life.Sherlock: Come, Moriarty! Come dance with me.
- Not until Watson uses his grapple cane to rescue Sherlock before he could fall into the water with Moriarty.
- Gnomeo and Juliet vs. the gargoyle henchmen.
- Watson gets a few.
- Watson's sudden death from plummeting off the top of the Natural History Museum from encountering one of the gargoyles... only that he survived from the help of his grapple cane, and the shatter heard was only a flower pot.
- He was the one behind kidnapping the gnomes, which was the only way he could get through to Sherlock. Sherlock even feels baffled about it and openly admits he beat him, much to Watson's delight.
- His Moment of Awesome comes in the climax where he's told to free the gnomes from Moriarty's pie filling. He does it by pouring soap and spraying water, from a nearby faucet, on them. And what's great is, he gets thanked for it.
