Continuity Nod / Kung Fu Panda 3

• Po has added even more action figures to his collection, including ones of Tai Lung, Master Croc, and the Wolf Boss. Because of course he would.
• After Po's first failed attempt at training the Five, they all walk/crawl bruised and battered towards him, similarly to how he did in the first film after accidentally stepping into the training exercises.
• When Po sees Shifu and all of the Five except for Tigress have been zombified, he says "Oh no, it's true, you guys have all been turned green! Except for you, Mantis. You were already green." followed by Mantis twitching his antennae in annoyance, similar to in the first movie when he says "Whoa, the Furious Five! You're so much bigger than your action figures! Except for you, Mantis. You're about the same." and Mantis twitches his antennae.
• After Po's failed attempt at teaching the Five, Shifu shows up and after telling Po about chi and how Po needs to be Po he leaves, leaving the lantern he had brought with Po as Oogway did in the first film.
• From the first film; Shifu gets momentarily distracted by something about his opponent that allows him to be incapacitated by a single blow. Secondly, his face gets smashed into a wok, much like his former student Tai Lung.
• In both the first and third films, the antagonist ends up with his own tail in his mouth once Po gets the upper hand in the fight.
• Shifu unrolls the scroll that holds the secret to Kai's identity. It's empty and Shifu is not amused, though it is revealed that he just had to unroll it further.
• When Shifu reads from the scroll detailing Kai's and Oogway's past, he reads too slowly, causing Mantis and Monkey to try and finish his sentences, just like Mantis did in Secret of the Five before he learned patience.
• Several elements from The Art of KFP make it into this one, such as: the abandoned junk in the desert (in the book it was the location of a Wretched Hive, in the movie it's where Crane and Mantis track Kai); Po's outfit in the Spirit World, which matches the Dragon Warrior costume from the storyboarded dream sequence from the first movie; the statues of the great kung fu masters around the stairs to the Jade Palace, which were originally intended to be a Vault of Heroes under the steps where Po was to have his final battle with Tai Lung; Tigress's new outfit, which is essentially the one from the book re-colored to gold; and even a number of shots of the panda village or the landscape during the journey there.
• Master Porcupine is a character that was originally going to be in the first Kung Fu Panda film, as a doctor using his own quills for acupuncture needles. He appears in this film as one of Kai's jade zombies, using his quills as arrows.
• Po accidentally dumps Sichuan peppercorns in his bathwater instead of soap and comments "My tenders!" while quickly adding cold water. Later, he suffers another Groin Attack while training an elderly panda.
• The bridge that Li and Po cross on the way to the panda village appear to be the same bridge where the Five fought Tai Lung in the first film.
• During the confrontation between Po and Kai at the end of the film, Po repeatedly mocks Kai's speech as he's delivering it as "chit chat". Or, in other words...
  Dragon Warrior: Enough talk, let's fight!
