Double Pounder

Double Pounder is a Bowser Jr. minigame in Mario Party 9. "Double Pounder" is also a term used by fast food chains to describe burgers. The gameplay of this minigame is similar to The Great Deflate, from Mario Party 4 and ID UFO from Mario Party 5.

Introduction
Bowser Jr. does a taunting dance from his platform. The camera then zooms out to show the players as well.

Gameplay
The duo must try to simultaneously Ground Pound switches of the same color. In order for that color switch to be activated, the players need to have almost perfect synchronicity. Whenever a switch is activated, lava spouts in the background, then hardens into a metal platform, which makes Bowser Jr. look nervous. If all four pairs of switches are activated within 30 seconds, the players win. Caution: if the players fail at activating all the switches, Jr. is victorious.

Ending
If the players are successful, Bowser Jr. will run off into a tunnel, and the players will hop along the platforms, giving chase. If they are unsuccsessful then the floor will fill up with lava and knock players away.
