A player about to cross the ice ledge during the Ice Castle level
At the beginning of the level, you will encounter only falling ice shards. Run along the top of the screen to avoid the ice. Make your way to the left and up the stairs. On the second floor you will enter a small room where you are taunted by the Frost King. Simply break down the door and proceed. As you enter the next area, you will need to cross a narrow bridge while being bombarded by a stream of arrows and magic. You'll need to listen carefully for the twing of bowstrings or the yell of the Frost King, as he cries out when he releases magic. Hold "block" as you move slowly to the right. This will deflect the arrows but you will need to leap over the ice magic. Making use of the Yeti's ability to prevent freezing can make this bridge segment far easier, as it allows the user to simply walk straight through the Frost King's magic without being frozen (note that the blasts will still cause damage, so this technique is only recommended for characters with moderately high defense). Defeat the Iceskimos at the end and then move into the Frost King's chamber.
Before crossing the bridge, however, you can eat a sandwich. This will allow you to easily get past the bridge and the arrows, creating a "human shield" for additional players, if there are any. A great animal orb to take while using this strategy is Yeti, as he prevents you from being frozen by the Frost King's magic (you will, however, still get damaged by the arrows and the Frost King's magic, but this is simply an easier way to get through the bridge part).

This battle is a lot easier if you have unlocked the Yeti animal orb in the Snow World level. While you can still be damaged by the ice, you will not be frozen by it. Keep moving around and then jump-attacking the Frost King when he appears. You should be able to string a line of midair attacks together to stay in mid-air and off the dangerous ground. As his health dwindles, he'll call more ice shards onto you faster and faster, until they drop at an almost ridiculous rate. Keep moving and attacking the Frost King until he's been defeated. The splash magic of the Red Knight and Orange Knight are especially useful here, as multiple hits make the Frost King's health deplete much faster. After the fight, a boss chest will drop and the Blue Princess will be saved.
- Watch along the side of the first section of the second floor for what looks like a piece of hanging ribeye, touching it will unlock the ribeye weapon.
- If Pazzo is taken along, he will paw at a place on the ground near the Steak. Dig at this spot to find the Ice Sword,but you don't need Pazzo to get it.
