The Tick Tock is an obstacle, firstly introduced as the second obstacle on American Ninja Warrior 8 in Los Angeles. The obstacle consists of a trapeze swing, in which competitors must swing from to reach a 100 lbs pendulum, which was 11 feet apart (the pendulum has a ledge on it). Then, competitors must work their way around this pendulum and jump off to the cargo net (10 feet away from the pendulum), which was attached on the landing platform. This obstacle is similar to the Double Pendulum, used in SASUKE 32, SASUKE 33, and KUNOICHI 10, except there is no trampoline and an addition of a cargo net. This obstacle proved to be much tougher for competitors, who mainly failed to reach the middle of the pendulum. Several competitors also had trouble dismounting, as they failed to swing enough momentum to hang onto the cargo net. A total of 43 competitors fell on this obstacle during Los Angeles qualifiers. In Los Angeles finals, the obstacle was modified, where the cargo net was removed (similar to the Double Pendulum), and a larger distance between the trapeze swing and the pendulum. Only Natalie Duran and Steve Seiver failed on this obstacle during Los Angeles Finals.The Tick Tock (renamed as the Tic Toc) returned as the second obstacle on American Ninja Warrior 9 in San Antonio. It proved to be just as deadly as the previous season, with another 43 competitors failed on this obstacle during San Antonio qualifiers. Only 4 women were able to complete this obstacle during San Antonio qualifiers (including Barclay Stockett and Kacy Catanzaro). However, no competitor failed on this obstacle during San Antonio finals.
- Tick Tock was designed/sketched after a punching bag.
- The obstacle originally was going to have two pendulums, but was decided to just have one pendulum due to it becoming far more difficult.
