Glitches in Kirby Super Star Ultra
Hyper Waddle Doo Glitch
Kirby must go to Planet Skyhigh and to a room with the Waddle Doo, entering the door on the right. Kirby should use Copy and exit. Kirby should use the copy beam on the Waddle Doo. If he does it correctly, the Waddle Doo should be running around until Kirby attacks or defeat it. If Kirby waits, the Waddle Doo walks in slow motion, and it falls into the pit.
Helper Phase Glitch
Kirby needs to go to planet Mekkai, and spawn a helper. Once Kirby and the helper get to the room with the wind, go to the left of that room, and the helper should begin walking against the wind, then turn left and right at a speed comparable to the Waddle Doo involved in the above Hyper Waddle Doo Glitch. The helper will then do a normal attack, slide back, walk forward, face left and right quickly, repeat. This may not work with every helper.
