Thing type 122, Spring Shell (Green), is a turtle-like enemy with a spring on its back used in Techno Hill Zone. Jumping into a Spring Shell from above will cause the player to be propelled upwards by the spring, potentially allowing them to reach higher-up platforms in the level. Compared to the yellow Spring Shell, the green Spring Shell's spring is weaker and does not propel the player as high. Jumping or spinning into a green Spring Shell from the side will destroy it, along with its spring. Therefore, a yellow Spring Shell is more suitable in situations where the spring is necessary for the player's progress through the level. Aside from the spring on its back, there aren't very many differences between this and a blue Crawla.
