Dino Skip Skip
Dino Skip Skip, often abbreviated as DSS, is a speedrun strategy used in the Cascade Kingdom that can save up to eight seconds in most major categories. The trick involves taking a shortcut to the upper level of the kingdom by climbing directly up the side of a rock wall near the start of the kingdom. This is achieved by landing on a very small piece of collision on the side of the wall that allows Mario to stand.
Some players have found it useful to imagine a rhythm to perform the inputs with the right timing. Video
Usage
Speedruns
In almost every speedrun category, Dino Skip Skip is used as an alternate method of climbing the kingdom to reach the Madame Broode arena. After the wall climb is performed, the player must perform Rib Jump to reach the highest level of the kingdom, allowing them to travel directly to the boss arena. As the name of the trick implies, this route variation completely eliminates Dino Skip from the route.
On version 1.0.0, the skip is performed immediately upon entering the kingdom, and removes both the standard First Moon Skip and Dino Skip from the route. In this case, the trick saves at least five seconds.
On versions 1.0.1 and higher (including version 1.3.0, the fastest version and the one used for most Any% speedruns), the trick is performed just after collecting Our First Power Moon, and saves a total of nine seconds since it also bypasses the cutscene where Cappy explains how to use the Odyssey.
It is to be noted that performing the skip on version 1.0.0 means that the rock containing Our First Power Moon will be unbroken during the skip. This causes the camera to continually attempt to center itself on the rock, making it much more difficult to get a good camera angle for the trick.
Koopa Freerunning
Dino Skip Skip is useful in the Cascade Kingdom Koopa Freerunning minigame, as it is the fastest method to get to the goal from the start. It saves around 3 seconds over the 2nd fastest method of reaching the goal. By extension, Dino Skip Skip is also useful in the speedrunning categories Koopa Freerunning RTA, All Moons, and 100% during Cascade Koopa Freerunning, which those 3 categories all complete at least once. It is not currently used in those categories as it is unneeded to get a good time, and the risk is not worth it at the moment.
