Fall

The title of this article is conjectural; an official name for the article's subject has not been found, so it has been given a fitting title by the editors. If an official name is found, then the article should be moved to its appropriate title.

Autumn is a special event in Super Mario World and its remake Super Mario World: Super Mario Advance 2. This event causes the appearance of Dinosaur Island to change colour and certain enemies to change their appearance. This event is triggered by completing Funky in the Special World in Super Mario World, and attaining all 96 exits in the remake.

Upon these prerequisites being attained, a short cutscene is shown, and at which point Autumn is triggered. Upon being triggered, Autumn cannot be reversed.

Changes

Dinosaur Island

Autumn causes Dinosaur Island to change colour, green coloured objects becoming brown, and brown coloured places (such as Chocolate Island) becoming green. Everywhere on the overworld map is effected, including places such as Valley of Bowser. Autumn will also effect non living objects, such as ground. Levels are not changed or effected at all. The intro of Super Mario Advance 2: Super Mario World will show Dinosaur Island in Autumn at the start and end of the intro. Although all of Dinosaur Island is changed, the water on the overworld map remains the same colour.

Enemies

Various enemies have their appearance changed in Autumn. This change only effects their appearance, they continue to act the same. Kuribons will be coloured yellow and wear sunglasses, Pokey segments will turn into small Thwomps, Jumping Piranha Plants turn into Jumping Pumpkin Plants, Bullet Bills turn into Pidgit Bills, all Koopa Troopas become Mask Koopas, all Koopa Paratroopas become Para Mask Koopas, and all Kamikaze Koopas have their multicoloured shell transformed into a multicoloured Mario mask.

Additionally, for Mask Koopas, all Red and Green Koopas are replaced by Blue and Yellow Mask Koopas, and all Red and Green Shells (stray or on a Koopa) are replaced by Blue and Yellow Mario masks. Koopa Paratroopas are not effected by this colour change. Although this change just effects enemies, this change also effects everywhere else in the game enemies appears, in-game or on menus. The intro for Super Mario World: Super Mario Advance 2 and the titlescreen demo of Groovy will change the enemies to their Autumn form (if they have one), and the ending of both games will show enemies in their Autumn form during the showing of most enemies in the game.

Although Pidgit Bills did not flap their wings and diagonally shot Bullet Bills (such as the ones on Vanilla Dome 4) were not transformed into Pidgit Bills even after Autumn, these were fixed in the remake.

Trivia

• It is incorrectly stated on Gnarly of Super Mario World: Super Mario Advance 2 that completing all the levels in the Special World would give the player a "special present". Although this is true in Super Mario World, it was changed in the remake.
