Neutral Special - Bone Attack - Papyrus holds his arm forward as an ethereal bone twirls before him like a baton. It continues to twirl while charging. When the button is released, it will travel forward at high speeds. At any point during its travel, Papyrus can click the button again, turning it blue. Blue bones don't hurt foes standing still, but if they're in the midst of moving, attacking, or shielding, it will hit twice as hard as a white bone.
Side Special - Electricity Orb - Papyrus lobs an orb forward like a shot put. If it hits the opponent, they'll be heartily zapped and thoroughly japed. Though it does little damage, it stuns the foe, making it easy to do a follow up attack.
Up Special - Cool Dude Leap - Papyrus delivers a two part recovery. First, he'll spring upward with a bone platform that says "Cool," and then can hit it a second time at any point to go even higher with one that says "Dude."
Down Special - Blue Attack - A very short ranged move. Papyrus holds out his hand, and if the opponent touches it, they get a blue tint to their color and HUD portrait. While blue, a foe's jump height is halved. This effect lasts ten seconds.
Final Smash - Special Attack - Papyrus calls forth his special attack, the Ga...wait, what's that dog doing here? And why did it steal the Smash Ball? The Annoying Dog travels at high speed around the stage, chasing the opponent. Papyrus just stands in the background yelling at the dog while it launches any foe it touches.
