The shield will deflect all enemy bullets, but the impacts will leave large cracks across the front of the shield, until the game reloads the image (it could overload the game eventually if it did not). The shield also greatly reduces explosive damage if pointed in the right direction, enabling the player to survive grenades and Claymores with little trouble.
A Bloonberry Bush is a Special Agent in Bloons TD 5. Once placed, it acts as a regenerating spike trap until the game is over. It grows five thorns per round, for a maximum of 200. Once the upgrade Tack Awesomizer is activated, the bush will be able to pop 400 bloons.
The Spike Factory is a special tower that, once placed, produces Road Spikes that pop bloons and disappear at the end of each round. Its special attack, Spike Storm, is capable of killing large amounts of bloons, destroying even MOABs and BFBs easily. Like the Dartling Gun, the Spike factory was not included in the original edition of the game. The tower was released on September 8, 2011. It costs 595 on easy, 700 on medium, and 755 on hard. On March 15, 2012, it was added to Bloons TD 5 as an update.
The Sentry Gun, also known as the Sentry Mechanical Firing Device, Sentry, Turret, or simply abbreviated to SG, is a building that can be constructed by the Engineer using the PDA, the Engineer's build tool.

Sput Sputs are dart-shooting statue heads found in Banjo-Tooie at Mayahem Temple. They are completely stationary, but shoots darts repeatedly at Banjo and Kazooie if they venture too close to it. A Sput Sput can be disabled by firing eggs at the yellow jewel on its forehead, or can be destroyed completely by hitting it with Grenade Eggs or having Golden Goliath kicking it. Such measures though are only temporary and usually not necessary since Sput Sput's darts are easily avoided, especially with the the fast-footed Talon Trot.
