You can place rows of single block crumble blocks in a 2 block wide shaft such that they alternate sides. Place too few and it's easy to springball (or sb) through, too many and it's a little ridiculous to get through in real time. You see a failed attempt of this in MDZ guarding plasma.

Quote from Rythyrix:
Any and all Spring Ball puzzles, with the exception of non-mockballable crumble block runs, can be done with bomb jumping.
I'm not entirely sure of what you mean by non-mockballable crumble block runs, but... Lies! The wys listed by Xaggoth are the ways currently known to make springball a necessity, but my R&D team is working frantically to discover more options.
I am the team. So progress is going a bit slow atm.

That's an unmockballable crumbleblock passage. It was a quick one.
You could have this statue/statuette/sign/orb/thing.
