Waddle Dee Steel Fortress

The Waddle Dees' Steel Fortress is an large enemy that has only appeared at the end of Stage 5 of Old Odyssey in Kirby: Triple Deluxe to date. It can be fought with the Hypernova ability only. Waddle Dees appear on the Fortress.

The Fortress can be destroyed by swallowing a missile shot by the fortress and firing it back at its segment with three wooden logs holding it up. Once done three times, each time with increasing difficulty, the Fortress will collapse, exposing the exit gate. The lower half of the destroyed Fortress serves as the platform that the gate rests on.

Appearance
As implied by its name, the Waddle Dees' Steel Fortress appears to be a large, tall metallic fortress that has the ability to shoot missiles at Kirby. It appears to have eyes with an angry appearance and a 'mouth' that shoots the missiles. Segments of the tower are divided by yellow bands. One of its segments contains three logs that hold up the rest of the tower above it. Attached to the side of the missile-shooting segment, there is a small platform that holds three Dees.

Trivia

 * The Waddle Dees' Steel Fortress is a part of a Kirby parody of the fairy tale, 'The Three Little Pigs', with Kirby taking the role of The Big Bad Wolf and the Pigs being the Waddle Dees. First, Kirby swallows a straw house, from which the Dees inside run away. Kirby then reaches and then inhales a log cabin, from which multiple Dees run. Further ahead, there is no brick house, but the Waddle Dees' Steel Fortress.
 * As the fortress becomes lower in health, the Waddle Dees inside become more frantic, running around in circles by the time the Fortress is defeated.
