Spoilers for this movie will be marked as usual. Due to its nature as a sequel to Pleasant Goat and Big Big Wolf - Moon Castle: The Space Adventure, however, that film's spoilers will be unmarked.
Pleasant Goat and Big Big Wolf - Mission Incredible: Adventures on the Dragon's Trail (喜羊羊与灰太狼之开心闯龙年) is the fourth movie in the Pleasant Goat and Big Big Wolf series, and a crossover of the character Xiao Shen Long from Dragon Club (小神龙俱乐部) with the Pleasant Goat characters. It premiered on January 12th, 2012.
There's turmoil in the dragon world, and since the dragons do different things to keep nature in harmony in the goats' world, it's affecting them, too. The goats and wolves must now team up with Xiao Shen Long to find the pieces of the Dragon Den's key and face evil dragons to stop the catastrophe.

This film had two follow-ups; the Pleasant Goat spin-off Pleasant Goat and Big Big Wolf: I Love Wolffy later in 2012, and The Mythical Ark: Adventures in Love & Happiness in 2013.
Mission Incredible: Adventures on the Dragon's Trail contains the following tropes:
- Camera Abuse: Sparky hits Tyranno-Rex with his 10,000-pound hammer, causing him to crash into and crack the screen.
- Continuity Nod: When Weslie and Wolffy are trapped under tons of debris after defeating the giant metallic dragon, Wolffy asks Weslie if he can take a bite out of him since he's traveled a desert and explored the moon, referencing the previous two films in the series (in the second film, an amusement park built over Goat Village uses up enough energy that it dries up the surrounding area and creates a desert that Weslie and Wolffy have to traverse, and in the third film the gang goes to the moon to defeat the Bitter Gourd King).
- Crossover: The film features Xiao Shen Long from the Chinese series Dragon Club as one of its main characters.
- Crystal Prison: A naturally-occuring bunch of crystals entraps Sparky at the halfway point of the film. He escapes by playing the full musical scale on the crystals, then performs a song he used to play with his mother so that he and the other goats can actually get past it.
- Dinosaurs Are Dragons: All of the dragons mostly lack attributes that are associated with dinosaurs. However, the villain is a dragon named Tyranno-Rex, referencing the Tyrannosaurus rex.
- Dismantled MacGuffin: The goats and wolves have to find the key to the Dragon Den, which is split into three parts which are scattered throughout the dragons' world.
- Dragons Versus Knights: The goats and wolves don brightly-colored knight armor as they go on a quest to stop the evil dragons from causing turmoil in the dragon world and, by extension, in the Green Green Grassland.
- Episode Discussion Scene: The promos are styled as behind-the-scenes interviews with the characters who discuss the movie.
- Fungus Humongous: The Dragon's World has lots and lots of giant mushrooms growing in it.
- iPhony: A flashback shows Jonie playing with a "Pear" brand tablet, a reference to the Apple company.
- Making a Splash: One of Xiao Shen Long's powers, the Gushing Faucet, has him creating a huge dragon out of water.
- Our Dragons Are Different: This film is about the goats fighting off evil dragons that have taken over the world. The series otherwise does not feature dragons prominently.
- Save Both Worlds: The gang has to save the Dragon World to also save the Green Green Grassland since the dragons that make the clouds, stabilize the soils and hold up the trees in the Grassland are reacting to the turmoil in the Dragon World.
- Self-Duplication: Xiao Shen Long has the ability to duplicate himself.
- Toilet Teleportation: When the dragons holding up the plants in the goats' world realize that their location is unsafe, they all escape from their underground cave. One of them happens to be using the toilet and escapes by jumping into it.
- What Happened to the Mouse?: In the previous movie, Wolnie's new babies are involved in a movie-wide arc about Wolnie's being pregnant with them; they only physically appear at the end of the film after being born. They are referenced exactly once in this film and never actually appear in it or any of the later films.
- Wings Do Nothing: Xiao Shen Long the dragon has wings but is never seen using them to fly.
- Wouldn't Hit a Girl: At the end, Wolffy appears in front of the gate to Goat Village with Wolnie and Wilie to help him destroy the gate with a cannon since he is badly hurt and in a wheelchair from the events of the movie. Weslie and the other goats don't know what to do since Wolnie is a woman and Wilie is a child. However, Wolffy isn't actually hurt and was just pretending so that he could use Wolnie and Wilie to help him capture the goats.
- Wouldn't Hurt a Child: At the end, Wolnie and Wilie help a badly-injured Wolffy destroy the gate to Goat Village with a cannon, and Weslie and the other goats don't know what to do since they don't want to hurt the child Wilie or the female Wolnie. However, Wolffy was only pretending to be hurt so that he could use Wolnie and Wilie to aid him in catching the goats.
- Wounded Gazelle Gambit: At the end of the film, Weslie manages to discover that Wolffy is pretending to be badly injured so that he can get Wolnie and Wilie to help him catch the goats.
