Big Chilly Blargg's Fort

Big Chilly Blargg's Fort is an anomalous frosty-themed level appearing in Super Mario 64. It contains a large castle made of ice and frost. This castle has a central tower which is surrounded by walls and a courtyard. The level has been reported to be accessed by the first version of the Painting Creator anomaly. However, the level has also been reported to replace a currently existing level or be accessed through one of the non-level paintings in Princess Peach's Castle.

Geography
Chilly Blargg's Fort takes the appearance of an arctic area with a re-used segment of Bowser in the Fire Sea, though the textures of this segment are changed to mesh with the level's icy theme, leading up to the castle. The castle itself is very large, and is made up of a circular wall containing a courtyard, and in the middle of the courtyard there is a circular keep. Atop this keep is a pool containing Chilly Blarggs. The top of the keep can be accessed by elevating platforms. Usually in the first star of the level: the titular Big Chilly Blargg, who is surrounded by 4 other Chilly Blarggs, appears in the pool. In all other stars of the level that have been reported: there are four Chilly Blarggs in the pool. More often than not, the level contains the Fire Flower power up and when it does, using it is the only way to defeat Big Chilly Blargg. However, when the Fire Flower does not manifest within the level, Big Chilly Blargg can be defeated some other way, commonly by jumping on its head.

Stars
The most common stars that have been reported to appear in this level are: an 100 coin star, an 8 red coins star, and a star for defeating Big Chilly Blargg, which is usually the first star in the level. Other stars have been reported, though these are unconfirmed.
