This could skip the boulder
Or the second option I tested but never performed
The boulder has an invisible wall you can flybash against...
The idea would be to make the contour of the boulder by flybashing against it
The problem is that you fall before the end of it
Since you didn't use a bouncer surface to start flybash, you fall down immediately if you stop sticking to the wall
The invisible wall does not go super far behind the boulder.
You could reach the other side with a extra jump
The problem is you barely need a second jump to go across the barrier on your left
So you don't have an extra jump to finish the skip
And you just fall all the way down
I'll try and see if I can flybash with a single jump
since we need the other one to get to the other side
I tested it with both asterix and obelix, but the idea is to use obelix to avoid all the cable car section.
