'''Mario Wings to the Sky''' is the fifth mission of [[Bob-omb Battlefield]]. To complete the objective and spawn the star, Mario must fly through five rings of coins and collect the [[secrets]], located in each ring's center.

There are 5 secrets, which are regions that Mario must pass through in order to spawn the star. Each secret as an origin point with a [[hitbox]] of 137 [[units]], cylindrically extending upwards by 100 units and downwards by 160 units.<ref>Secret and Coin Hitboxes: https://youtu.be/H6L5rpuGxYI</ref> All secrets have a coin overlapped onto it with the same cylindrical hitbox of a radius of 137, but only extending 64 units up and 160 units down. Additionally, a ring of 8 coins is present vertically encircling the secret.

Previously, on August 31, 2013, pannenkoek2012 collected the star with 1 A Press, which was used to launch from the [[cannon]] with a [[wing cap]] to collect the secrets in the traditional way. At the time, it was believed that constructing a [[goomba bridge]] by [[cloning]] is impossible, as the game has a limited number of object slots that can be used, and techniques of making more efficient goomba structures were not discovered yet. The method to create a goomba bridge that requires the least number of goomba clones at the time requires an exponential number of clones.

The TAS run was completed on May 29, 2015. It took 55 hours to create, with 2 years of planning, resulting in a run that takes 56 minutes to finish. The HOLP takes 28 goombas to reach, the oasis consists of 7 goombas, and the final [[goomba staircase]] takes 36 goombas to bridge up the oasis, totaling 71 goombas to complete the mission.

In order to create a goomba oasis at the ideal location, a specific HOLP needs to be achieved beforehand. Precisely, the HOLP is set at (x, y, z) = (3592, 5170, -42). In the single-star basis, the HOLP can be achieved by building a goomba staircase consisting of 28 Goombas. The process would take 22 minutes to complete<ref name="comparison">BoB MWttS Faster HOLP Real-Time Comparison: https://youtu.be/tKabwMxQ3Qo</ref>.  

For the first, second, and third secrets, Mario uses [[shell hyperspeed]] in order to build up high negative speed to launch off from the mountain, allowing the lower three secrets in the air to be collected.  

In the ABC run of this star, the goombas in the oasis created by transport cloning are in the following positions<ref>https://imgur.com/a/HANeE</ref> according to Pannenkoek:

CCC Challenge stands for Coinless, Capless, and Cannonless. The restriction of coinless was already difficult to circumvent, and at the time the coinless run was made, it was thought to be impossible. However, as more advanced techniques such as [[goomba cluster]]s, [[PBH|pause buffered hitstun]] and [[Parallel Universe]]s were found, Pannekoek began planning a route to get the secrets without collecting coins and without the aid of Wing Cap and cannons.

In Bob-omb Battlefield, the ring of coins surrounding the secret is only loaded one frame after Mario enters the activation radius, and not on the frame Mario activates it. Therefore, there is a one-frame window where Mario can collect the secret without touching the coins, but in order to do so, Mario needs to be move at more than 2000 speed<ref>BoB Coinless Secret using Hyper Speed: https://youtu.be/j7nY_Fu1HPE</ref>, which is 10 times faster than the speed used in hyperspeed flying with wing cap in 120-Star TAS speedrun.

To execute this strategy, Pannekoek constructs a [[Parallel Universe|PU]] route. For the first secret, Mario reaches negative 1.66 million speed (3.83 million for the second secret) by pause-buffered BLJs ([[Backwards Long Jump]]) to navigate to "midway point"<ref name="PU">According to Pannenkoek's workshop (https://imgur.com/a/Qg91o), the "midway" point is (x = -1, z = -5) in the PU grid for the first, third, and fourth secret, and (x = -11, z = -4) for the second secret. The "hill" point is (x = -2, z = -2) in the PU grid for all 4 secrets. Mario will also cross a "midair" point at (x = -1, z = -1) for one frame before reaching the secret. </ref> with an [[Overflow Jump]] (OJ), dropping down to 0.98 million speed (speed drops are done by rapidly pressing A) in order navigate up the hill<ref name="PU"/> with another OJ, and finally dropping down to about 404 thousand speed to horizontal launch back to the main map while collecting one of the secrets. In order to have Mario stop exactly on the main map collecting the secret, the movement is set so that his final launch movement has one of its [[Quarter Step]] being out of bounds.
