The Bobble hat is one of the eight receivable hats and scarves that can be obtained by completing one of the Christmas holiday events that occur once per year. This also rewards the player with all other holiday items associated with Christmas. It matches the Bobble scarf. If lost, players can get a replacement from Diango in Draynor Village. It is a holiday item and purely for decoration.

Before the 2013 Christmas event, it could only be obtained from picking one up from various spawn points around the world during 12 August and 19 August 2013. When picked up by a player, it would immediately spawn in another random location.

This item can be stored in the toy box space of a costume room, as part of the 2005: Woolly hats set. Ultimate Ironmen may be unable to retrieve individual pieces until the full set is stored.
