Fall

Fall, or Autumn , is an unlockable alteration in Super Mario World and its Game Boy Advance remake Super Mario World: Super Mario Advance 2. This event changes the appearance of certain enemies, and alters the color palette of the overworld map of Dinosaur Land to reflect the season from Spring. The theme is unlocked by completing Funky in the Special Zone in Super Mario World; in Super Mario World: Super Mario Advance 2, it is unlocked by completing all 96 exits. Once these prerequisites are reached, a short cutscene exclusive to the GBA remake is shown: Luigi is shown on a hot air balloon tossing masks down with a message stating "Mario and Luigi have found all of the goals. Congratulations!!! Now you can play a slightly different Dinosaur Land!". After this, Mario is seen running, where he jumps on a Koopa Troopa and takes its shell. A mask falls, and the Koopa walks to it and starts wearing it. The scene then cuts back to Luigi tossing masks, with Caped Mario attending Luigi. Super Koopas then appear, where they then carry a large sign saying "Congratulations" and Mario and Luigi flash their to the player. Once Fall is activated, these changes cannot be reversed unless the save file is deleted and a new game is started.

Dinosaur Land
Fall causes Dinosaur Land to change color, with green objects becoming orange-brown and brown places becoming green. Everywhere on the overworld map is affected, including places such as the Valley of Bowser. Although all of Dinosaur Land is changed, the water on the overworld map remains the same color, and the visual appearance of the levels is not affected. The intro of Super Mario World: Super Mario Advance 2 will show Dinosaur Land in Fall at the start and end.

Enemies
Various enemies have their appearance changed in Fall. This change affects everywhere else in the game enemies appear in, including on menus and during the credits. These changes affect their aesthetics only.


 * Piranha Plants and Jumping Piranha Plants have jack-o'-lantern heads, and the latter are also known as Jumping Pumpkin Plants.
 * Bullet Bills become Pidgit projectiles and are also known as Pidgit Bills. In the original Super Mario World only, there is a quirk that causes the diagonal and vertical Bullet Bills of Vanilla Dome 4 to not change. They also visibly flap their wings in the GBA remake.
 * Koopa Troopas and Koopa Paratroopas wear Mario masks instead of Koopa shells, and the former are also known as Mask Koopas.
 * Green Koopa Troopas and their shells become Yellow, and Red Koopa Troopas and their shells become Blue. However, all other Koopa Troopas' and Koopa Paratroopas' colors are unaffected.
 * Goombas are yellow and wear sunglasses (Super Mario Advance 2 only).
 * Pokeys' segments turn into saws (Super Mario Advance 2 only).
 * The intro for Super Mario World: Super Mario Advance 2 and the title screen demo of Groovy change the enemies to their available Fall form, and the credits sequence of both games show enemies in their Fall form.
