In Mega Man X, what weapon does Mega Man X get from Chill Penguin?

In Mega Man X, defeating Chill Penguin awards Mega Man X the Shotgun Ice weapon. It fires a large ice projectile and is the signature special weapon associated with Chill Penguin, one of the game's eight Maverick bosses.

Mega Man X follows the series tradition in which defeating a boss grants access to that boss's weapon. Shotgun Ice is especially useful against Flame Mammoth, because its ice element exploits that boss's weakness. Using the weapons in a strategically effective order is one of the game's central design features.

The names Snow Storm, Freeze Cutter, and Ice Blast can sound plausible because they fit the game's elemental naming style, but they are not the official weapon name in the original game. Shotgun Ice is also notable because its charged version creates a frozen platform-like projectile that X can ride.
