Finding bonus warps:
In GG Boost or Scramble mode, there is the ability to find Warp Bottles, or Bonus Warps. These bottles are unlocked by doing something to earn an Extra Bonus in the middle of the fight. You must then open the barrel that you find before the level started and you will see that the item has changed into a Warp Bottle. You must take this in the middle of the fight. After the battle is finished completely, the Warp Bottle takes its effect. You are entered into a bonus battle, usually having to deal with breaking falling barrels or defeating a Leopaldon-esque suit of armor that will not move or attack you. After the battle is finished, whether positive or negative, you are immediately sent to the end of the stage against Robo-Ky II. When you defeat him, you are sent to the next stage in a various mission where you will begin again.
