Tedhaun is a secret mini-boss in Kirby Squeak Squad that only appears once Kirby has collected all of the pieces of the Ghost Medal. Tedhaun will fly out of the Medal and replace one of the mini-bosses in each world with himself.
Tedhaun attacks by summoning small explosive ghosts to surround him and block oncoming attacks. Occasionally he will chase down and attempt to grab Kirby, immobilizing him long enough for one of his minions to explode in your face.
If the player is able to defeat Tedhaun, they will receive the Ghost ability, which let's Kirby possess and control almost any regular enemy in the game.
