D.U.A.L.

"A huge twin-hulled monstrosity that hauls fellow Bloons into battle. Although fast, it's weak for its size - best to focus on its payload!"

The D.U.A.L. (Dastardly Ultra-heavy Airship Lifter) is a support blimp that begins to appear after round 110. Weak on its own, the D.U.A.L. instead spawns with another blimp in the wave and carries it into the fight. As it is fast for a blimp, this can ruin unprepared or single-tiered defenses.

Statistics
Speed: Equivalent to Green Bloon.

Durability: Takes five thousand hits to pop. Does not have any defense.

First appears in: Round 110.

Children: None if not carrying a blimp. If blimp is being carried, releases the blimp as well as twenty Ceramic Bloons.

Abilities
The D.U.A.L. has only one ability but it allows for it to support Bloon advances easily.

The Long Haul - Carries a random blimp. The blimp in question can be up to the Z.O.M.G. in size with no limit on how powerful the targeted blimp is beyond size. The blimp being carried will be immune to all damage when it is being carried. The blimp is returned to the path after being carried halfway through the track.

Trivia

 * The D.U.A.L.'s appearance is based off of the catamaran, a twin-hull boat design.
