Sticky Sap Plant is a special mission in Bloons Monkey City. There are two plants with sticky sap on them that have the same ability as Glue Strikers, with Glue Soak and Corrosive Glue effects. Also, some of the track is glue-covered and will slow bloons down. This tile needs to be captured to build the Superior Adhesive Factory which allows for the Glue Striker ability. Upon completion, the player will receive the Extra Sticky Substance item as well as cash and XP rewards. When playing, the player receives one third of the normal amount of money received from popping bloons, so Banana Farms are recommended.The mission has 22 rounds, and two MOABs are sent on the last one.
