The Aerwhale King idly flies around the Platinum Dungeon, in a circle. It may be provoked with any physical attack, however this is not recommended.
Any player that steps on a Songstone within 30 blocks of the Aerwhale King, will trigger the attack cycle. If it's attack target leaves the top of the tower, the Aerwhale King will reset.
He is able to pass through any blocks, and is not affected by them. This does not include the dungeon itself.
The Aerwhale King will charge at it's attack target, knocking them away when hit. If this attack misses, the Aerwhale King will be stunned for 60 in-game ticks, or 3 seconds. The damage delt by this attack entirely bypasses armor.
- The way the Aerwhale King idles around the dungeon was actually inspired by the airships in New Super Mario Bros. Wii.
