Trivia
Note: Once you use the Mighty Dragon on a level you didn't beat yet, you cannot use him for an hour unless you clear the level that you used Mighty Dragon on.
 * This episode commemorates the fifth Chinese Zodiac, the Dragon and is the second Chinese-specific episode, the first being Moon Festival.
 * The Orange Bird appears for the third consecutive episode of Seasons and its fourth appearance overall (the Orange Bird also appears in Birdday Party in the original Angry Birds game). It also debuts the Orange Bird's first appearance in a chinese holiday-based episode in Seasons.
 * In the episode, the Mighty Eagle is replaced by the Mighty Dragon, and the sardine prism is replaced by a Red Koi Fish
 * This is the the first world where Gold Blocks appear.
 * A Year of the Dragon Comic strip was released with a story based on the animation of the same name.
 * Fun Fact: In the Year of the Dragon comic, it turns out that Mighty Dragon, mistakened for Mighty Eagle, seems to be a "picky eater". As you recall in page 2, when he ate the sardines that the Yellow Bird offered, he said, "What is this canned junk? Bring me fresh food!" He also didn't like the fruits and vegetables the Yellow Bird offered in page 3 and angrily said, "You call this fresh food?!" When the Red Bird, Yellow Bird, and Blue Birds went to Mighty Eagles lair to ask the Mighty Eagle for help in page 10, they were shocked that "Mighty" is actually Mighty Dragon all this time and at the same time, he said, "Nihao, Mighty's little friends!". In page 11 when Mighty Dragon noticed the Koi Fish on the Red Bird's fishing rod, he said, "I can't stand Mighty's canned junk! Speaking of which, any chance you want to share that one?" Then, in page 12, the Yellow Bird said in relief, "So that's what he meant by fresh food!" So they used that Koi Fish to foil the Pigs' plan in pages 12 through 14.
 * Red wood is used in the Year of the Dragon.
 * An animated short for this episode debuted on January 21, 2012. It was the second to premiere first on television (on Nickelodeon) rather than online.
