Trivia / Yoshi's Island

  • Name's the Same: The theme for the cave levels is called "Crystal Caves". There's also a level in Donkey Kong 64 called "Crystal Caves".
  • Real Life Writes the Plot: Notice how in this game and successive Yoshi-themed games that if you complete them with top marks, you get a red flower drawn on your results? This is actually a tradition/cliche in Japan dating back to primary schools where if the teacher is especially pleased with your work, you get a flower circle drawn on the paper. Essentially, the Japanese version of getting a gold star in America.
  • Recycled Set: The Advance version recycles sounds originally used in Yoshi's Story.
  • Market-Based Title: Most likely to play on the success of Super Mario World, the original game was named Super Mario World 2: Yoshi's Island in North America and Europe, despite the fact that it is a prequel. In Japan, it was simply called Super Mario: Yossy Island. In all countries, the Super Mario World 2 part is dropped completely from the GBA port, in favor of Super Mario Advance 3.
  • Sequel Gap: Twice. DS was released 11 years after the original. Yoshi's New Island was released eight years after DS.
  • Trope Namer: For Ground Pound.
  • What Could Have Been: There may have been points in the game where you control Baby Mario himself without the star, as there are Dummied Out sprites featuring him crawling and even a Yoshi-less victory pose.
    • There are also unused transformations for Yoshi in the game, including a mushroom, a plane, and a walking tree.
    • There's an oft-told story that Shigeru Miyamoto's bosses at Nintendo were so impressed with the original Donkey Kong Countrynote  that they wanted this game to go in a similar direction, which Shigeru Miyamoto disagreed with, creating the well received crayon-style graphics as an act of rebellion.
