Winter Windster

"The blue in front of the Goal will try to attack from midair. Ooh! Chilling! Listen, I bet if you stick something in one of those magma holes, magma might shoot out! Oh, one more thing... Don't look at its red!"

- Spriteling

The Winter Windster is the boss of Shivering Mountains and is fought by Wario in the game Wario World. It is the first boss of Thrillsville, and it is succeeded by Spideraticus and Red-Brief J.

Battle
The Winter Windster's arena is a large irregularly-shaped block of ice with four small magma pools on it. The arena is surrounded by sharp ice spikes.

It uses a variety of attacks in his battle. It can attack by breathing a stream of cold air, which will freeze Wario, leaving him vulnerable to be headbutted by the Winter Windster. The Winter Windster can also duck into one of the lava craters in the arena and send out pulsing shockwaves of energy which will hurt Wario upon contact. It also shoots blue energy missiles. The Winter Windster's final attack is the "Evil Eye" attack, which will cause it to phase out into bursts of energy if Wario looks into his eyes when they start glowing red. The energy causes Wario to be inflated, which causes him to float over the spikes outside the arena. The player can allow Wario to regain control before he lands on the ice spikes by shaking the Control Stick quickly. To avoid the attack, Wario has to turn backwards without looking at the Winter Windster's eye.

Throughout the fight, it drops explosive boulders from its cloud, which can squash Wario if the boulders land on him, but Wario can also toss a boulder into one of the lava craters, causing an explosion of lava to be sent out. The lava can be used to knock the boss from the sky if it is over that crater. Once the Winter Windster is close enough, Wario can quickly punch it to daze it, and then use a Mad Move on it. The Winter Windster is defeated after hitting it with five Mad Moves. After the battle, Wario is able to access Beanstalk Way.
