Super Glue

Super Glue is the final upgrade in the third path for the Glue Gunner in Bloons TD 6. It shoots pink globs of glue that briefly immobilizes and very slightly damages bloons, including M.O.A.B-Class Bloons excluding the B.A.D. It costs $Unknown on Easy, $Unknown on Medium, $Unknown on Hard, $Unknown on Impoppable.

Trivia

 * Due to the attack speed of the tower, it is possible to completely immobilize the B.F.B and Z.O.M.G on Rounds 60 and 80 respectively, allowing the player a very long time to to almost anything, including farming with Jungle's Bounty.  Note that due to the very slight damage, the bloon will be popped eventually, albeit after about an hour or more.
 * Note that this may be a problem on C.H.I.M.P.S as if the bloon is stunned outside the range of other towers and money is not avaliable, the player must wait until it is popped by the Glue Gunner.
