Ice Cap

The Ice Cap is a supposed cap in Super Mario 64. It functions the same as the Ice Flower, which first appeared in Super Mario Galaxy, oddly. It is the opposite of the Fire Cap.

Fire & Ice Caps in the Frigid-Fire Fields
Fire & Ice Caps in the Frigid-Fire Fields is the cap switch course that usually unlocks the Fire Cap and Ice Cap. It is a large field split into 2 halves: ice and fire. The ice section has light blue grass, and the fire section has red grass. The fire section is for the Ice Cap, and the ice segment is for the Fire Cap. The ice section is full of ice blocks that need to be melted using the Fire Cap to progress. It also uses the unused cracked ice texture on specific ice cubes. The fire section functions the same as the ice section, but it instead has large flames that have to be put out with the Ice Cap. There is an orange Cap Switch for the Fire Cap, and a light blue Cap Switch for the Ice Cap. The player can collect both caps at the same time to switch between throwing fireballs and ice balls. There is also a red coin star, with half of the red coins being in the fire section, and half of the red coins being in the ice section.
