I don't have C2 around to double check, but have you tried using the pin behavior to pin the platforms together in sequence using the bar type pin (to keep all the platforms the same distance from eachother), then just move the lead platform?
That should work for the skull boat type movement. The way the blocks appear in the first two examples would take a bit more work.
When I get home from work I'll try to come up with something, if you haven't figured it out by then.
