Autumnal Battlefield

"¿Mirando por este pagina en Español? Tú la encontraras aquí."Autumnal Battlefield is an anomalous level found in some personalized copies of Super Mario 64, being an Autumn variant of Bob-omb Battlefield as the name suggests. This level is different from a case of Dynamic Level Rearrangement as most reports claim that there is some change to the level geometry itself, such as the unused river segment of Bob-omb Battlefield being present. This level also reportedly has a unique evening skybox and remix of the BOB theme. This level is most commonly accessed by entering Bob-omb Battlefield when the Internal Clock detects it is either evening or Autumn.

Description
Autumnal Battlefield is near identical to Bob-omb Battlefield in most reports, though there is usually some difference, usually having some unused asset of the map like the spike at the top of the mountain or the unused river, though other reports reference a village-like area, more floating islands, or some open field area where the Chain Chomp is most commonly present. Several reports also claim there is a sky area similar to Wing Mario Over the Rainbow above the main area of Autumnal Battlefield. Most enemies in this level are also in the regular version of Bob-omb Battlefield, though some other reported enemies that appear are Fly Guys, Lakitus and Piranha Plants. Several reports notably claim that this level is harder than Bob-omb Battlefield, though exactly how isn't consistent.

Missions
Most missions in this level also appear in Bob-omb Battlefield, such as a race with Koopa the Quick or a boss fight with Big Bob-omb. Other reports notably claim that there are missions that commonly appear in BOB due to Notable Star Relocation, such as the Easy Way Out. There is also reports of finding a star in the sky area, finding 5 secrets in the trees of the level, and simply climbing the mountain in the level to find the star on top.

Theorizing
This level is likely a case of Dynamic Level Arrangement, seeing as to how similar it reportedly is to Bob-omb Battlefield except for some geography changes. Alternatively, the level may have been changed to the modern Bob-omb Battlefield, likely due to this level being too difficult for a first level or the developers deciding that it should be a more general theme instead of specifically Autumn. However, it might have been removed alongside the Internal Clock if it was initially dependent on it and coexisted with Bob-omb Battlefield.

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.
