Waddle Dee Army
From the Super Mario Wiki
Waddle Dee Army is King Dedede's Final Smash in Super Smash Bros. Brawl. King Dedede blows a whistle to summon many Waddle Dees, Waddle Doos, and Gordos that charge across the screen to deal damage. While Waddle Dees simply ram into the player, Waddle Doos give an electric shock on contact, while Gordos deal a high amount of damage and knockback, but stay on screen for the shortest amount of time. Characters on the ground are also pulled toward Dedede during the move if they are nearby.
