Thing type 552, Blue Spring, is a blue spring pointing straight up. Compared to the yellow spring and red spring, it has a low amount of force behind it, being weaker than both the yellow spring and red spring. The blue spring propels the player 166 fracunits into the air, which is a little higher than normal jumping height. It is ideally used for bodies of water too shallow for yellow springs, but too deep for a player to jump out of.
