Goblin

The Goblin is a small, stealthy unit -- the fastest unit in the game. Their first target is resource buildings making them the ideal troop to deploy if your primary concern from a raid is collecting resources. They deal double damage to resource buildings (gold mines, elixir collectors and storages for each). This means that they deal more than 2x as much damage as Barbarians and 3x as much as Archers to these types of buildings! The trade off is their relatively low health which is higher than an Archer but lower than a Barbarian. Also, because the nature of the character is to attack resource buildings first, ignoring all defenses, they can be vulnerable to attack and should not be deployed without another type of troop for support.

The goblin's appearance is that of a small green creature with large pointy ears, red eyes, and a red tipped nose. Goblins wear brown pants and shoes. They also have a large sack for carrying resources stolen from your enemy.

Strategy
Goblins are great for stealing resources. First, use wall breakers to clear a route to storages and mines/pumps. Then, use barbarians, giants and other higher HP units to distract mortars and wizard towers while the goblins deplete the resources.
