I placed some enemies nearby in this area to trick the player into shooting down the pole. Instead of making a convenient bridge, the pole bounces off the spring and seals off the carrot assuming you're not down there like I am in the screenshot. Different springs bounce the pole in different strengths. A red spring will typically bounce the pole up and down until it settles into the upright position again. Green and blue make it bounce back toward the side you shot in from like in the screenshot.
