Autumnal Battlefield

Autumnal Battlefield is a supposedly cut version of Bob-omb Battlefield that some players have accessed. It is very similar to Bob-omb Battlefield but with an autumn theme. It contains several of the same enemies, but is said to occasionally have enemies not regularly seen in Bob-omb Battlefield. It shares the same song with the aforementioned course, and is considered more difficult than the regular Bob-omb Battlefield. It also often has an exclusive skybox of an evening sky.

Missions
This level appears to have several stars identical to Bob-omb Battlefield, and has been reported to have every mission from Bob-omb Battlefield. Some different stars include simply climbing to the top of the mountain, or collecting 5 secrets throughout the level.

Theorizing
It is unknown as to why this version of Bob-omb Battlefield was scrapped, though it was likely due to the increased difficulty. It is also possible that this was created by the personalization A.I. to challenge the player.

Report No. 1
"So I was playing a new copy of Super Mario 64 I found at a garage sale- that sounded cliche, didn't it? Whatever. Well I started a new save and went into Bob-omb Battlefield and it was Autumnal Battlefield. It wasn't the Bob-omb Battlefield I remembered from videos and seeing friends play it as a kid, that's for sure. Big Bob-omb was relatively normal, and so was Koopa the Quick, though the floating island was new. Though no matter how hard I tried, the Chain Chomp kept killing me before I got the star, so I never saw the other missions."

Trivia

 * Similarly to Autumnal Battlefield and Bob-omb Battlefield, Gold Leaf Galaxy in Super Mario Galaxy appears as an autumn-themed mirror of Honeyhive Galaxy. It is possible that Gold Leaf Galaxy was based off of Autumnal Battlefield, though this is unconfirmed.
