[Papyrus snickers again at the pun, releasing his brakes to better roll back and forth on both legs. Feeling similar enough, smooth enough. But the notion that his new head decorations look like hair...]

You think so?? [He runs his hand (singular) through the cables, testing how well they bend or sway with the motion.] Still don't know why, wearing a helmet... made robot hair? [Maybe there's a pun about helmet hair and static electricity in there somewhere, but nothing that flows well enough to be a plausible explanation for the timing of this change.] Styling it... won't be like the movies. But! I'm sure I can figure... something out.

[They're more like braids or locs than strands of hair, so far. And that's not something he can easily change - they grew from his skull, or maybe through it, to connect to the helmet. He can try splicing them into smaller casings, but he's not about to go adding to the places they emerge from. Not while he's got some skull left.]
