Arena Waddle Dee refers to the unnamed Waddle Dee boss in The Arena of Kirby Super Star. He can be defeated by being inhaled or by hitting him. His role is replaced by Bandana Waddle Dee in Kirby Super Star Ultra.
Another Waddle Dee with the same behavior as his makes an appearance only in one of three mid-boss all-stars rounds in the Boss Endurance sub-game of Kirby & The Amazing Mirror, although this one is explicitly named "Waddle Dee" and given a Waddle Dee's more usual colors.
- The Arena Waddle Dee is the only boss in Kirby Super Star that did not appear in its remake, and is the only one who is exclusive to The Arena, as he is replaced by Bandana Waddle Dee.
- Arena Waddle Dee and Bandana Waddle Dee are the only bosses that can be defeated by Kirby's inhale.
- The easiest way to defeat the Arena Waddle Dee is to simply inhale him, because he is like a regular Waddle Dee in every way in the game, except with much more health.
