Timing

The attack can be extended by mashing the special move button, which also affects the duration of the clean hit. The timings shown are for the shortest and longest possible durations.

Clean hit	12-25 (shortest) 12-24 (longest)
Late hit	26-46 (shortest) 25-79 (longest)
Windbox	12-46 (shortest) 12-79 (longest)
Animation length	104 (shortest) 137 (longest)

• The landing animation is longer (30 frames → 40), increasing the time before Kirby can activate a held Assist Trophy after it.

Parameters

To determine the duration of the attack portion, the move encodes a value known as rotation speed, which is affected by several intricate factors. Rotation speed starts at 130 when initiated, and decays by 2 every following frame (frame 13 onward), with the attack portion stopping if the value drops to 60 or lower. Mashing the special move button increases rotation speed by 7 per input, though it still cannot exceed 130, and there are several limits to the inputs; a delay of at least 5 frames between them, a maximum of 20 inputs total, and a window of 60 frames (effectively frames 13-72 of the move) for inputs to be accepted. Furthermore, after the input window ends (frame 73 onward), the rotation speed's decay is increased to 3 per frame. This ensures that mashing can only extend the attack's duration for a certain amount of time. Further complicating things is that if an input is made during the 5 frame lockout window for making inputs, an additional 5 frames are added to the remaining lockout time, further extending the time before another input can be accepted. The lockout also applies for the first 5 frames of the spinning portion of the move, shortening the effective window to make inputs to 55 frames, and meaning that making an input during the first 5 frames will also further delay when inputs can be made, shortening the window even more. This makes it possible to both over and under mash, which combined with the very short window to make inputs can often result in mashing failing to extend the duration at all.

The attack's hitbox timings also take the rotation speed into account. The late hit is actually coded to occur on frame 1550 of the attack portion (1100 prior to version 8.0.0), but for each real frame, the move advances an amount of frames equal to the current rotation speed. For example, with the initial speed of 130, the move advances from frame 12 to frame 142 within two real frames of its initiation, or from frame 1 to 131 of the attack portion specifically. This is why mashing to increase the rotation speed shortens the clean hit's duration instead of extending it.
