Moneybag's Domain
Supposedly a secret area found in Snowman's Land in early versions of the game, nearly a few weeks away from its retail release. The way of accessing the area varies, though it is most commonly accessed by having a nearby enemy knock Mario through a wall into a hidden warp. The area is a large, flat surface, similar to that of The Princess's Secret Slide, but with tons upon tons of coins. The exact number of coins in the area is uncertain, as the copies that contained this stage are rare, though it's theorized to be somewhere in the hundreds. Due to the amount of coins in the area, the game tends to lag a lot, and can even crash if the player isn't careful. There are more than enough coins to summon in a 100 Coin Star, and collecting it warps the player to the main floor of the castle, considering the star as one of the castle's secret star. Due to the number of coins in the area, the player can create multiple 100 Coin Stars in the area, although they all count towards the same star. It does not have an official name, though fans have nicknamed the area "Moneybag's Domain" due to the amount of coins it has. It is theorized that the area was a test map, used to test how many coins can be in one area/on screen at once.

Small Chill Bullies
In the files of Super Mario 64, there are unused smaller variants of the Chill Bully boss that function identically to regular Bullies. In some personalized copies, they can appear throughout Snowman's Land, being defeated by being knocked into the freezing water, or in place of the regular Chill Bully, in numbers ranging from 1-5 according to several reports.

Bob-Omb Battlefield Remix
Similarly to Autumnal Battlefield, there are reports of the stage being a remixed version of Bob-Omb Battlefield with a snowy theme. The geometry and layout of the level is near-identical, but changes include patches of ice and a snowy skybox. All of the missions are mirrors of ones found in Bob-Omb Battlefield, right down to the Red Coins being located in the same places. Instead of Bob-Ombs, the level is reportedly inhabited by the unused smaller Chill Bully. Since Big Bob-Omb doesn't make an appearance, his role is instead given to the big Chill Bully, who is defeated by being punched off the top of the hill rather than being thrown. The music is seemingly a remix of Bob-Omb Battlefield with instruments from Cool, Cool Mountain, such as sleigh bells. It is unknown what causes this remixed level to appear, but it is theorized that the level was always intended to be a continuation of Bob-Omb Battlefield. The name Snowman's Land is a play on "no man's land", which refers to the space of land between two opposing armies in war.
