Stickier glue

BTD5 icon

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 longer on bloons and can slow them down to one-third speed. When combined with Corrosive Glue, it is highly effective because it gives time for the glue to dissolve the bloons more effectively.
