When using Bros. Flower or Ice Flower, it is a good idea to have the sound at a good level so you can hear when the fireball or iceball switches to the other character . Although pressing both Bros. at once is an easier way to ensure you are always throwing with the character with the big fireball or iceball, doing this shortens the time you have to attack. If you only attack with the person with the fireball or iceball as perfectly as you can. you will gain more time, allowing more damage and possibly use it up to the maximum time. All Bros. moves have a maximum time.
