The Spring Fling is an obstacle, used as the third obstacle of the Qualifier in Season 4's Spring Wipeout, replacing the Snow Plow Sweeper from Winter Wipeout.
Contestants must launch themselves onto a swing by using the object provided to them (a trampoline, a diving board, a green ball, or a zip-line), then make their way to the end and leap onto the sloped landing platform.
For Summer Wipeout, to remove its association with spring, it was renamed the Mood Swing. It was now interchanged with the Jiggle-ator as the first post-Big Balls obstacle in the Qualifier. It works exactly like the Spring Fling, though it was the only type that had a turntable, a slide, and a trapeze.
In episode 16 of Summer Wipeout, it was referred to Lover's Leap, because it was a Blind Date episode, and it once again had a green ball to bounce on.
It was replaced by the Snow Fall on the next season.
