The Boo Balloon is a community-created misc for all classes. It is an orange balloon reminiscent of a Jack-o'-Lantern that floats behind the player's shoulder.
This item can only be worn around Halloween or during a Full Moon; at other times of the year, it does not appear in gameplay, unless the server has Halloween mode enabled. However, it can be equipped at any time and can still be viewed on the loadout screen even when it is not visible during games.
The Boo Balloon was contributed to the Steam Workshop under the name "Sinister Souvenir".
