ID UFO

ID UFO is a 2-vs.-2 minigame from Mario Party 5.

Introduction
A UFO startles the Red Team members, and it quickly flies off into space. While the Red Team turns to face the screen, the screen splits and shows both teams.

Gameplay
There are two sets of UFO pairs, one for each team. The team must Ground Pound two of the ten UFO panels simultaneously within a time window to match the UFO pair outside. When a panel is triggered, color and sound effects indicate whenever a player has a correct match or not. Once the team correctly matches their pair, their UFO pair flies away and a new UFO pair appears. The team that matches five UFO pairs before the other team wins and ends the game.

While all the UFOs' designs are unique, most share a few characteristics designed to confuse the player into guessing the wrong panel.

Ending
The team that wins do their victory animations while the other team falls through the holes and floats in space. If no teams have any UFO pairs, the minigame ends in a draw with both teams falling through the holes.
