The music is accidentally left out in the Previously On segment of episode 3 of the Great War in the Bizarre WorldStory Arc. As a result, the segment feels very empty.
The English version of Joys of Seasons episode 6 has the spoken dialogue significantly delayed on the YouTube version and all of the audio delayed on the iflix version.
Episode 68 of Joys of Seasons has two brief instances where the animation is inadvertently replaced with a multilingual "Media offline" screen for a split-second. This only applies to the English version, which later got a second upload with the error corrected (though the original version with the error was kept as well).
The English version of Mighty Little Defenders episode 6 originally had the spoken dialogue, but completely lacked music and sound effects save for the theme song and end credits music. This episode was later reuploaded with the audio fixed.
Cash Cow Franchise: It's one of the most popular animated television series in China, thus causing it to make quite a bit of money off of its merchandise.
Channel Hop: This series has aired on a handful of channels throughout its run, among them CCTV-14, Hunan TV's Aniworld, and ZJTV.
Completely Different Title: The Hindi title is entirely different. It's Kya Bakra Hai!, which translates to What a Goat! in English.
Content Leak: Due to briefly being unlisted and hidden, some episodes of the English dub of Mighty Little Defenders were found by fans a few days before their intended release date. Once these episodes were privated until they were intended to come out, fans made copies of them early.
Stage 5 at its peak in China, due to having a lot of seasons and merchandise. It slowly cooled down to stage 3/4 when people grew tired of it, but it looks like it might reach stage 5 again as it's gaining back popularity.
It's always been in stage 0(a) in the West due to a complete lack of exposure to the show, though it's slowly inching towards stage 1 or possibly 2 due to fans spreading the word about the show and getting people interested.
Xi Di Di/Little Brother Happy or Xiao Xi Ur/Little Happy for Weslie.
Hui Da Guh/ Big Brother Grey or Hui Da Xu/ Old Man Grey for Wolffy.
The goats (and Wolnie sometimes) tend to be called just by their adjectives (lazy, etc.). Or the goats are called in the same "format" as Weslie's nicknames.
An anthropomorphic flower character appearing only in Pleasant Goat Fun Class: The Earth Carnival episode 16 (and no other episodes) is popular among English fans. She has been nicknamed "Bloom Sister" due to not having an official name.
The show as a whole is sometimes nicknamed Xi Hui, which is based off of the Chinese title.
A few of the English dubs are accessible if you know where and how to find them. However, the English dub of the first season's Great War in the Bizarre WorldStory Arc, which was on DramaFever before it shut down, has not resurfaced apart from a very small handful of episodes and clips (again, if you know where to look).
The websites that hosted early manhua strips went down and CPE didn't put all of the manhua strips on their app, making some early strips hard to find.
Late Export for You: South Korea didn't get the fourth and fifth movies (released in China in 2012 and 2013 respectively) until 2020.
Long-Runners: It started around 2005, and it is so popular that it now spans 2,000+ episodes, with no signs of stopping. Basically, it's to China what SpongeBob SquarePants is to America.
Marathon Running: Some seasons air really quickly due to their popularity. For example, The Athletic Carousel aired 60 episodes in only 4 days.
The Merch: There are over 1,000 different products aimed at different demographics, including fashion products, home goods, skin products, school items, and different toys and electronic items.
Milestone Celebration: The seventh film, Amazing Pleasant Goat, was made to commemorate the franchise's 10th anniversary.
This show is referenced a bit in Happy Heroes. Given that the director of Happy Heroes was also one of the higher-ups on the team creating Pleasant Goat, it makes sense.
One of the monsters is sent flying by Happy S., and is later shown to have landed in a dark ominous place with Wolf Castle in the background.
Big-head Monster: He hit me so hard I have no idea what cartoon I've ended up in!
When Big M. and Little M. are wolves in the fairy tale arc, Big M. remarks that he has suddenly developed a fear of frying pans... then he got hit with a frying pan.
When Mr. Lightbulb is trying to introduce television to the citizens of Planet Mystery, he mentions that one could see shows on it. Aqiang points out that he could do that too, and dresses up as a wolf and says "Dearest sheep, I've arrived!"... Mr. Lightbulb hits him with a frying pan.
The streaming service iQiyi has a search bar. Before you type something in, the search bar might have the placeholder text Pleasant Goat and Big Big Wolf.
Release Date Change: The season Mighty Little Defenders was originally slated to premiere in the summer of 2018, but the production team was forced to change the episodes so that they were less violent. This caused the season to be delayed to January 2019.
Rereleased for Free: Quite a few movies/shows originally costed money to watch before they were put up for free on Youku, iQiyi, and other sites. However, this didn't last because they eventually made you pay to watch some seasons.
Sequel Gap: From 2009 to 2015, the series released at least one theatrical film per year. The announcement that the eighth film would be released in 2021, six years after the seventh film, Amazing Pleasant Goat, broke this pattern.
Movies came out at a pretty steady and consistent rate up until 2015. After the 2015 movie came out, fans had to wait 6 years for the next movie to come out in 2021.
Mighty Little Defenders was due to air in summer 2018, but they had to edit the show to make it more suitable for children and families. Because of this, it was delayed to winter 2019.
Talking to Himself: Quite a few of the original Chinese actors voice more than one character at a time:
Zu Liqing as Weslie, Night Wolf, and White Handsomey.
Gao Quanshang as Slowy, Dark Handsomey, Master Paopao, and Brother Tai.
Liang Ying as Paddi and Wilie.
Deng Yuting as Tibbie, Jonie, and Fragrant Wolf.
Liu Hongyun as Sparky and Banana Wolf.
Zhang Lin as Wolffy and Yellow Wolf.
Troubled Production: Mighty Little Defenders had a troubled development for half a year. The National Radio and Television Administration forced Creative Power Entertaining to edit the fighting scenes to make them more suitable for kids. They also forced CPE to change the weapons. This caused the season to come out much later than expected.
