Glue Hose is the 3rd upgrade of Path 2 for the Glue Gunner. This upgrade makes the tower shoot glue more than 3x as fast and glue twice as much bloons with an update, allowing many more bloons to be glued, and, if paired with Corrosive Glue, popped. This tower, along with other glue towers, should generally be placed at the beginning of the map for the best effects. It is nearly useless late in the game in BTD5, when most bloons are M.O.A.B. Class Bloons.
This upgrade returns in BTD6 as the third upgrade of Path 2. As with all Glue Gunners, it can now target MOAB-class bloons. However, it can also prevent other Glue Gunners from targeting MOAB-class bloons if coated with said glue. It costs $3250 on Medium.
