Springs are items that appear on platforms in Doodle Jump. When jumped on, springs propel you up 352 points. They are the most common transportation devices, and they boost you the least far up. The achievement "Serial Springer" on the iPhone versions of the game tells you to jump on a Spring 3 times in a row. The achievement "Super Serial Springer" tells you to do the same, but with 5 springs in a row. You can also get this and those achievements when you get nearly 40000, there will be five springs and probably one moving monster between second and third spring. Jumping on all 5 springs in a row may earn you both achievements.
