''Serendipity the Pink Dragon'' is a 1983 anime (original title ''Serendipity Monogatari Pure to no Nakamatachi'' -- "''Serendipity Stories: Friends on Pure Island''") that was adapted into a movie in 1989. The story follows Bobby, (or Kona in Japanese), a young boy who is shipwrecked in the Antarctic. He finds a pink egg and floats on it out to a magical island, where the pink plesiosaur Serendipity hatches. The island where she lives is endangered by the threat of humans coming when Captain Smudge realizes there is gold on the island.

The original anime, and the movie made from it, was based on a series of children's books called, oddly enough, Serendipity Books. Each book was designed to deliver AnAesop, such as "[[BeYourself Enjoy being you,]]" [[TheGoldenRule "Treat others the way you want to be treated,"]] and "Not everyone enjoys the same things."


* AdaptationExpansion: And how! The original Serendipity Books were mostly stand-alone stories with different characters and settings (with the exception of a few mini-series here and there). Serendipity herself only appeared in one or two books, the plot of which the anime and movie only follow quite vaguely.
* AmbiguousGender: A baffling example in the English dub, Peela-Peela is referred to as a female in the first half of the movie and a male in the second half.
* AscendedExtra: Lord Winston manages to be both this and DemotedToExtra at once. He gets a lot more screen-time and characterization than in the original story (wherein he was only known as "the Dolphin"), and is a fairly important character, but he's no longer [[spoiler:one of the rulers of the sea]].
* BecauseDestinySaysSo: The speaking stones' prophecies. Although PropheticFallacy and LoopholeAbuse often apply.
* BishieSparkle: Often with Princess Laura
* ButNowIMustGo: At first played straight, then subverted with Serendipity.
* CantGetAwayWithNuthin: Peela-Peela, at first, but then he/she ends up becoming a KarmaHoudini.
* CarnivoreConfusion: Bobby eats a coconut, but they ''talk'' and have feelings...
* CassandraTruth: Without proof of the island's existence, Smudge is reduced to ranting which is promptly ignored by the other humans.
* DemotedToExtra: The Walrus. He barely appears at all in the film when in the book he was the first character Serendipity met after hatching, helped her to make her journey across the ocean, and was [[spoiler: the other ruler of the sea]].
* DinosaursAreDragons: The title calls Serendipity a dragon, but the theme song says she's a dinosaur.
* EggMacGuffin
* EverythingTalks: Rocks talk, the fruits on the trees talk, etc.
* ForTheEvulz: Captain Smudge- "What's that bird doin'? Well, it's a shame I'm in such a foul mood-" *cocks gun to shoot Peela-Peela*
* GoshDangItToHeck: From Bobby at one point. "What the heck was that?"
* HeWillNotCrySoICryForHim: ''Literally'' true for Princess Laura--because she is a princess and not allowed to openly express her emotions, there is a race of creatures on the island that will do it for her. When she is sad, they wail and produce [[OcularGushers endless streams of tears]]; when she is happy, [[{{Keet}} they bounce around joyfully]].
* HumansAreBastards: Humans are the main threat to the island.
** HumansAreSpecial: ...except Bobby, who defends it and is thus viewed as an exception (eventually).
* LostWorld: The island is this to some degree; this is the reason its discovery by Smudge is so exciting to him, and so distressing to its natives.
* LullDestruction: The dub movie has several songs filling quiet moments and quite a bit of extra speech.
* MightyWhitey: Shades of this with Bobby, since the island and its denizens need him to save the day. However Serendipity plays as much of a role, and Bobby's race is never exactly clear despite his pale skin. (Which just makes it a case of HumanityIsSuperior.)
* NowWhichOneWasThatVoice: The anime does credit actors at the beginning, but never stated who voiced which character. Worse is that many of the names lead to no one. The only close actor is Michael Sorich who voiced Smudge due to his voice being similar to Morton from Swiss Family Robinson.
* SeadogBeard: Captain Smudge has one.
* SugarBowl
* TalkLikeAPirate: Captain Smudge
* YouGottaHaveBlueHair: The mermaid princess Laura has purple hair.
