Glue soaks through all layers of Bloon.
~ BTD6 Description

Glue Soak is the first upgrade of Path 1 for the Glue Gunner in Bloons TD 6. It allows glue to soak through all non-MOAB-class layers. The next upgrade, Corrosive Glue, or adding MOAB Glue is required to target MOAB-class bloons, but the glue will never soak through them under any circumstance.

It costs $170 on Easy, $200 on Medium, $215 on Hard, and $240 on Impoppable.


Glue will now soak through all non-MOAB-class layers, so no matter how many layers are popped all descendant bloons will persistently have glue until the glue wears off by time. This will never occur with MOAB-class bloons, however, no matter what other upgrades are added.

The Glue Gunner gains an old-fashioned hat. When paired with any crosspath, all that changes is the addition of a hat. The hat is removed when upgrading further to Corrosive Glue.



Mainly for soaking through tougher bloon layers from the Black tier and above, ensuring the affected bloons slow down much further even while passing the Glue Gunner.


  • Glue Soak does not soak through MOAB-class bloons under any circumstance, unlike the description of the upgrade.
  • If needing to soak bloons at more than three layers, this upgrade is helpful.

Version History[]

Glue Soak remains unchanged since the game first came out.

  • The description for Glue Soak is ambiguous; the glue doesn't actually soak all layers of bloon, as it never soaks through MOAB-class whatsoever.
