Ducking is a technique in every installment of the Punch-Out!! series excluding the 1984 arcade and Micro vs. System games. It can be used to evade attacks that can't be dodged or blocked. In Punch-Out!! featuring Mr. Dream, it is performed by rapidly pressing down on the Control Pad twice. In Punch-Out!!, it can be performed one of three ways depending on the control scheme used by the player. When playing with the Wii Remote and Nunchuk, pressing down on the Control Stick activates the maneuver; when playing with only the Wii Remote in both hands, blocking is done by pressing down on the Control Pad; finally, when playing with the Wii Balance Board, applying pressure to its middle with both feet causes Little Mac to duck. Ducking does not evade most uppercuts, or attacks were your opponent punches straight down.
Sometimes you need to duck like the Bear Hug.
