Cant animate single face

Hey all, im new here and quite new to blender.

I want to animate a spider like object but only certain faces, everytime i try using keyframes, and IPO curves it wont let me, it just wants to scale the whole object, and not just certain points, ive added some pics of how i want it to be scaled, hope that helps! Thanks in advance!

You can use armatures, hooks or shape keys.

Thanks for the quick reply, i ended up using hooks and cant believe how easy it was! Thanks again!
