- The Sneaky Goblin is a Super Troop based on the Goblin. It can be unlocked by boosting the Goblin when the Goblin is at least level 7, and when the Town Hall is upgraded to level 11 or higher.
- Boosting the Goblin requires 50,000 Dark Elixir and doing so allows the Goblin to be boosted for 7 days. The level of the Sneaky Goblin you obtain from the boost corresponds to the level of the Goblin you have.
- The Sneaky Goblin is an improved version of the Goblin that does more damage and has more hitpoints. Its Cloak ability enables it to remain invisible for 5 seconds after it is deployed.
- Sneaky 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, Sneaky Goblins consider the Clan Castle or the Town Hall to be resource buildings regardless of whether or not they contain loot and whether or not the Town Hall is at level 12 or 13 and has its Giga Tesla or Giga Inferno triggered; Sneaky Goblins will preferentially target them in addition to causing double damage to them.
Once all resource buildings are destroyed, Sneaky 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.
