Stickier Glue is an upgrade for the Glue Gunner. It costs $100 on Easy, $120 on Medium, $130 on Hard and $145 on Impoppable. It makes glue last twice as long on bloons (12 seconds to 24 seconds in BTD5 (?)). When combined with Corrosive Glue, it is highly effective because it gives time for the glue to dissolve the bloons more effectively.
