Goblin (Clash of Clans)

The Goblins in Clash of Clans are troops that can be unlocked by upgrading your barracks to level 4. They also attack your base in the tutorial, and fail. They target loot as first choice, and do double the damage to buildings that have loot in them.

Trivia
Although they normally prioritize the buildings with loot in them, they are seen to go after the cannon first in the tutorial, which results in all of them dying.
