Springs are quite common and are used to increase the height of the Doodler's jump. Springs can be on a moving or regular platforms, but can not be on a vanishing or exploding platform. Spring can have different appearances such as a coiled coral plant or a spring flower (get the joke?) but otherwise are just a coiled piece of metal. Springs appear in all games and can be used or ignored. You can get several springs in a row and unlock achievements or just use it in gameplay.
