In the Japanese games, Super Mario World's "Forest of Illusion" and The Legend of Zelda's "Lost Woods" share the name, "Mayoi no Mori" (Lost Forest). All the standard exits in the Forest of Illusion send you around in circles, which is comparable to the Lost Woods circling you back to the entrance after a wrong turn.

The two ammunition-based enemies in Super Mario World are Bullet Bills and Torpedo Teds. This would make their referred-to names 'Bill and Ted', a possible reference to the film "Bill & Ted's Excellent Adventure". Their Japanese names translate as "Killer" and "Torpedo" respectively, meaning this reference would have been made by the Nintendo of America localization team.

The game originally had a flying cage carried by four winged creatures. Mario would start already in the cage and with an autoscroll script, the cage would move along the level. Although the cage can be found in the code, the graphics for it are incomplete. The cage is likely left over from the 'SNES Test Program'.
