Fly
From the Super Mario Wiki
This article is about the Super Mario Galaxy move. For information about the enemy first appearing in Mario Bros., see Fighter Fly.
In Super Mario Galaxy Bee Mario and Bee Luigi can preform the ability fly. This is done by pressing or holding A after jumping. When Mario starts to fly a meter will appear, going down and down, changing colour from green to red. Once the bar is empty Mario will fall down to the ground unable to fly anymore. It is also possible to let go of A at anytime when flying; then press it again before touching the ground to fly some more, if Mario has some flight left.
The meter will refill after Mario touches a flat surface, and no other time. This allows Mario to fly again. If Mario touches water while flying he will lose his Bee powers and his flying ability until he touches another Bee Mushroom.
