Party Animal is a Bungie.net multiplayer medal available in Halo: Reach. It is earned by playing a game with Birthday Party enabled for all players. It is represented by the Birthday Party icon on top of a gold eight-pointed star. The medal does not appear in-game and can only be viewed on Bungie.net.
On March 31, 2012 Bungie.net ceased updating Halo game stats and player records, transferring all record-keeping responsibilities to Halo Waypoint. As Party Animal could only be viewed on the site, it is effectively no longer awarded.
