snake not caterpillar movement along follow path

[zoesan]

I've been practicing with the follow path, and want an object to appear as though its moving (its similar to the wooden fish you find with separate body parts,) but can't find how the Z axis might be able to be used if at all with the follow path tool, any suggestions welcome. Also currently if I use the draw path tool to draw a wiggle line, its corner points only, can't get the bezier's to appear on the points in the line, even when I click on the bezier feature, this may give me something else to work with that might help.

I've worked out that 'sharp corners' needs to turned off for beziers. Have 'sheared' the line for follow path, and used the 'rotate layer xy tool' it looks visually correct on screen, but now the line moves along with the object but not along path.
