How to Build a Dragon is the fourth episode of the ninth season, and the 88th overall in LEGO Ninjago: Masters of Spinjitzu that was released on July 10th, 2018, in Singapore, and will be on July 21st, 2018, in Australia.
- The title of this episode is a pun on the popular Cressida Cowell book series and DreamWorks movie franchise, How to Train Your Dragon.
- This episode is similar to The Forgotten Element in that, both include the Ninja as the captives of a villain who is exploiting their Elemental Powers, and building something in order to escape.
- Oddly enough, Iron & Stone features the Ninja, being forced by this power-exploiting villain (though Iron Baron hadn't learned about their powers at that point), to fight another power user for the villain's entertainment.
- Iron Baron exclaims "Manure! I hate manure!" after being covered in dragon dung, referencing the iconic line of the character Biff Tannen in the Universal Pictures film trilogy, Back to the Future.
- It's revealed by Karlof that Chamille has possibly become a villain, Skylor confirmed that Bolobo was captured by the Sons of Garmadon, and Griffin says that the Serpentine refuse to help the Ninja due to the Time Twins using snakes as their army.
- Harumi is nearly killed by Garmadon, but she is saved by revealing that she knows the location of The Resistance's base.
- Garmadon's method of trying to kill Harumi is similar to Darth Vader's preferred method of execution—telekinetically choking his subordinates who fail him.
- Jay's flashback is revealed in this episode.
- Garmadon's army plans an ambush on The Resistance's base.
- The Ninja escape the Hunters' grasp and free the Dragons.
- Iron Baron orders his followers to hunt down the Ninja, due to them humiliating him.
- The Firstbourne is seen for the first time.
- Dareth temporarily gets Elemental Powers from drinking tea, confirming one of the three April Fools spoilers.
- When Kai approaches and befriends the Wind Dragon, he is in his Sons of Garmadon outfit.
