Turbo Charge
From the Super Mario Wiki
Turbo Charge is an attack that Watt used in Paper Mario. This attack will cost Mario 3 FP, and Watt also needs to be leveled up to the Super Rank. To execute this move the player must press the A Button as the red stars light up. Mario's attack power will then be temporarily boosted. For how long it´s boosted depends on how often you hit the star(up to 4 round)
