Toughness Waddle Dee

Toughness Waddle Dee is an invulnerable type of Waddle Dee introduced in Kirby: Triple Deluxe. This Waddle Dee is only found in the lower area of the Copy Ability Test Room, which is unlocked after the player completes the game's story mode. The only purpose of the Toughness Waddle Dee is to act as a training dummy for Kirby.

Toughness Waddle Dees have so far only appeared in Kirby: Triple Deluxe, where they served the same purpose as the training dummies found in the Copy Ability rooms of Kirby's Return to Dream Land and Kirby's Dream Collection: Special Edition.

Appearance
The Toughness Waddle Dee has the same basic appearance of a standard Waddle Dee. However, unlike the basic Waddle Dee, the Toughness Waddle Dee had metallic silver skin everywhere except for its face. They are also completely immobile, unlike typical Waddle Dees.

Special Abilities
The Toughness Waddle Dee is unique from normal Waddle Dees in that it is both completely invincible and immobile. It simply stands, unmoving, in the middle of a small room until Kirby begins attacking it. It is also unique in that it does not deal any damage to Kirby in the event Kirby collides with it. However, colliding with the Toughness Waddle Dee will still cause Kirby to be knocked back and gain invincibility frames, as if he had been damaged.
