Whistle Soldiers are enemies in Kirby's Epic Yarn. They are one of the four soldier enemies in the game; the others being Sword Soldiers, Spear Soldiers and Cannon Soldiers. While Sword Soldiers are the most common soldier enemies, Whistle Soldiers are the rarest. They do not appear in every level a Soldier is found in, however one is encountered in Toy Tracks of Treat Land. No more than one or two Whistle Soldiers can be found in a level, making them much rarer than the other three. Whistle Soldiers are red and black creatures with a red and black eye. They wield a yellow whistle. Whistle Soldiers do not attack at all. When they spot Kirby or Prince Fluff, they will jump and blow their whistle. Their whistle causes Sword Soldiers and Spear Soldiers (possibly) to appear from the sky. Kirby and Prince Fluff must then fight off the summoned Sword and Spear Soldiers while the Whistle Soldier pulls out two flags and starts cheering and dancing for them. A Whistle Soldier can be defeated. They can also be rolled up into a yarn ball and tossed at the other Soldiers they have summoned. A Whistle Mariner is the Whistle Soldier's rarer, aquatic "brother". Whistle Soldiers will have a confused look if they are jumped on.
