Quoted from Beatnik-Filmstar:
I believe this last one requires the right orbit before the snikt! shot as well. I don't think just plunging straight into a snikt! shot does it. Sure as Hell could be wrong though. Hell - I've never even done it on purpose. The handful of times I've pulled it off were after missed tries for the 3rd shot listed. Plunge - Orbit - Katana shot bricks perfectly and ball ends up on left flipper - Snikt! in time to still register.
You don't need to hit the right orbit for the Super Secret Skill Shot, I can definitely confirm that. There are 2 ways I can suggest to accomplish this from my own experience:
* Luck - I've had the ball catch some crazy spin on the plunge, so my attempt at a Super Skill Shot through the Katana took an odd trajectory and went right off of the Snikt. Total fluke but it has happened to me a few times.
* Trap up - if you can control the ball coming out of the left orbit you have a little bit of time here to hit the Snikt. Not a lot but if you can get it under control and over to the left flipper quickly without hitting other stuff, you should have a shot at collecting this if you hit the Snikt.
To be honest though, if you are attempting the MKV skillshot (right orbit + katana) you might just hit the Super Secret by accident.
