Hi all gurus !

I try to create a octopus but i don't get it right... the sketch I made in Cinema4D (lower right picture) so you understand what's shape i'm trying to achieve. Please put me on right track.
I start with a shape in topview and a rail in front view and then I tried to Rail Revolve but i dont achieve the right shape. How should I do that ? Thanks in advance !
