Profile
Super Mario World 2: Yoshi's Island Nintendo Player's Guide description: '', step aside. The real jungle explorer is here! Join Yoshi and Mario for a trek through tropical treetops and lagoons. Watch out, though. Some shrewd chimps would love to throw a monkey wrench in the proceedings! Meanwhile, the natives are restless, especially when Yoshi and Mario invade the ruins of a lost civilization. Some seriously scary water life lie in wait, too. When things get too damp, Yoshi morphs into a submarine.''

Trivia

 * The level point of 3-5 on the map is surrounded by cave-like terrain, even though 3-5 does not take place underground. Meanwhile, 3-6 is a cave, and its level point does not have that terrain surrounding it.
 * Similarly, 3-3 is also shown as a cave on the map, but it is not a cave level either.
