Introduced in Sticky Steps, suction cups at the end of a rope allow to attach the rope to the surface. With a tap on a suction cup, it is released, and the tap on the screen reattaches all suction cups in the level. They are mainly used to prevent the candy from breaking or leaving the screen. If a candy can be moved by bees or ants while attached with a suction cup, the rope will get stretched and turn red, thus allowing the candy to gain a great velocity.
Novice wall climber and Veteran wall climber achievements are awarded to the player after using suction cups.
