How to practice RockCrocking in 20XX:
- Select a lvl 1 Captain Falcon or Ganondorf CPU
- Go to YS, DL, or FoD
- Get the CPU to about 60-70% and then freeze their percentage by pressing Y and up on the d-pad at the same time
- Make sure you are hit yourself to at least 15% so that the CPU's up-b knocks you down so you can tech.
- Send the CPU off the stage with an ftilt or whatever move. Make sure they are far enough away off stage to where it looks like they will have to up-b in order to recover.
- Press right on the d-pad to create a save state right before the CPU is about to double jump.
- Keep pressing left on the d-pad to load the save state you made so that you can keep getting the CPU in the same position to where you just run off and get hit by his up-b.
- Practice RockCrocking.
Heads up: You'll likely have to spam the left d-pad in order to get the CPU to actually be off stage like you had it in the first place. Also note that loading a save state while you are grabbed by Falcon or Ganon's up-b will result in your character model being bounded to the bottom of the opposing character, but you will still be able to move and be completely invisible n ****. Sometimes. This doesn't freeze the game, but if you got the CPU stuck below you, just stomp it a few times until it "dies" and then run off the stage and kill yourself. It should be fine after that. If you are the one that is stuck on the CPU, just keep upsmashing it to oblivion and then hold in a direction to have your invisible character walk off the stage.
