Moving Blob

[mindspan]

I want to create a animation of a moving ameba across a bed of cellular tissue. I would like it to move by extending an arm, the arm sticks to the ground and spreads out a little then pulls the body to the extended arm as the arm becomes part of the body again. This action is repeated with other extensions thus moving the blob.
I don't know the best way to go about this. The motion must look organic and can't be to heavy because I will have multiple blobs in the scene.
Any ideas would be great!

Have you explored a combination of joints and clusters?

I was thinking of some combination of particles and clusters but don't know how to have differend sized particles in the same cluster.

Maybe you could setup a rig where you would turn on IK for a given arm, move it to its goal, then switch to FK and move the body to the goal. Use SBD or nCloth to add an organic feel to the body.
