The Goblin is the fourth troop unlocked in the Barracks.
Goblins prioritize resource buildings above all other targets, and will bypass all other types of enemy buildings and troops while any resource buildings remain on the battlefield. This is true even if they are under attack by enemy Clan Castle troops, heroes or Skeleton Trap skeletons. Note that like all troops that prioritize resources, Goblins consider the Clan Castle and the Town Hall to be resource buildings regardless of whether or not they contain loot and whether or not the Town Hall's weapon (if any) is activated; Goblins will preferentially target them in addition to causing double damage to them.
Once all resource buildings are destroyed, Goblins become like any other troop with no preferred target; they will attack the nearest building to them regardless of type, and will turn and attack enemy units if they become aware of any nearby.
