"A chibi-style, sentient ‘Ctrl+Z’ button with stubby legs and a round body. Its glossy surface features bold, engraved text, and it waddles with a determined yet ominous stare. Glows faintly when near mistakes but only erases the ones you wanted to keep. If pressed too many times, reality glitches and resets to 3 seconds ago. Its expression shifts between mischievous and indifferent, embodying chaotic undo energy."
