Squeaky Sheets

Squeaky Sheets is a guess-the-identity game for six or more players.
The players are divided into two teams.
One team leaves the room and covers one of their players with a sheet/blanket and other accessories to make the other team's job to figure out who is underneath as difficult as possible.
The player covered to be almost unrecognizable re-enters the room walking, crawling on all fours or creeping. He/she crawls into the centre of the room and then the opposing team makes a guess regarding the identity of the player.
If they are wrong then the sheet-squeaker makes a squeak and another guess is made. If the guess is correct, the team who made the correct guess gets one point. The teams change places.
If both guesses are incorrect the sheet-squeaker awards his/her team a point and crawls back out of the room to be replaced by another member of the team.
The game continues in this manner until one of teams reach a certain point (e.g. three) and win the game.
